I screwed up My GVC VPN connection.. UGGG

RageRage Newbie ✭

GVC Connection works but cant get out to web

I am using the GVC client, with a old TZ100 that has a GVC licence on it.

I need to have all traffic pass through the NAS to allow the client to use the WAN ip.

** So no split tunnels...


1. The client does connect.

2. The client gets an IP and gateway (And they look correct)

3. I can navigate the LAN no problem.


The issue I am having is:

4. No WAN/Web.


What did I miss, I "assumed" since the Client PC got the correct gateway it would use it to surf the web etc.

** I know it should work it did in the past on the same hardware, just not sure what to look for.


Cheers

    Hi,

    I dont see the NAT policy in the second screenshot that would forward the traffic to the Internet from the VPN clients,

    Please create below NAT policy :

    Original Source: Any

    Translated Source: X1 IP

    Original Destination: Any

    Translated Destination:Original

    Original Service: Any

    Translated Service: Original

    Inbound Interface: X1

    Outbound Interface: X1

    Please try to disable the connection and then reconnect again after the NAT is configured.

    Thank You !!

    Still having the issue

    At this point I can Global VPN in via client, and can ping LAN addresses.

    I can not ping 8.8.8.8 (Default DNS)

    So (I assume) my issue is not DNS

    I tried to ping google and it showed me and odd address likely IP6.

    I was able to cut and paste that address into chrome and I did get to the site, but not to any ip4 addresses.

    Hi @Rage ,

    What is the error message on web or the ping repsonse you get when trying to access any IPv4 address ?

    Can you do a capture on SonicWALL only for ICMP traffic and generate the traffic from clients for Ipv4 address (ping 8.8.8.8 or 8.8.4.4) and let know what is packet status for that traffic hitting sonicwall.

    Please check the logs on sonicwall, probably you can filter based on the IP address and get some hint from event logs as well.

    Hi @Rage,

    I think we may be missing out the access rule in SonicWall for Internet access for VPN users. Could you please check for the access rule from VPN to WAN? If you don't see a rule in this VPN to WAN section, please feel free to add one after taking a configuration backup once. For instance, the rule can be of Any, Any, Any, Allow format.

    In case if the access rule is already in place, I think the best way to determine the reason for not being able to ping 8.8.4.4 or access Internet would be to capture packets at the firewall level. We will use built-in packet tracing tool in the SonicWall called 'Packet Monitor' in this situation.

    Please follow below steps,

    • Navigate to INVESTIGATE | Packet Monitor.
    • Click on "Monitor Default" to clear out any previous capture parameters.
    • Click on "Configure"
    • In Settings Tab, disable all the check boxes.
    • Navigate to the "Monitor Filter" tab and specify the only fields as shown below,
    1. Ether type:   IP
    2. IP type:    ICMP
    3. Destination IP:   8.8.4.4
    4. Enable the checkbox “Enable Bidirectional address and port matching" and other check boxes should be left unchecked.
    • Navigate to "Display Filter" Tab, ensure all fields are empty and enable all check boxes.
    • Navigate to the "Advanced Monitor Filter" tab and enable all check boxes.
    • Click "OK" to save the parameters.
    • Click "Start Capture".
    • Click OK, and Start Capture.
    • Try to initiate the ping to 8.8.4.4 from the VPN client PC.
    • Please click on Refresh option in the packet monitor page to see the traffic.
    • Once the necessary packets are captured, click on "Stop Capture".

    Please check for dropped packets or packets not getting NATTED. This will helps us to isolate the issue and figure out the solution. I hope this helps out.

    Please post here for any further questions or clarifications.

    Hi @Rage ,

    We see the log as 05/05/2020 22:31:19.080 Info Network Access ICMP packet allowed 184.105.97.80, 3, X1 8.8.4.4, 3, X1, dns.google ICMP Destination Unreachable, Code: 3

    Can you please check if the WAN Remote access network is included for the user and also for Trusted User group under VPN access list ( OR the group that is selected under WAN group VPN ).

    It is strange that IPv6 is working and not IPv4 taffic. So can you please check if there is an access rule available for both Ipv6 and Ipv4 taffic.

    At the client side ty to do a traceroute for the 8.8.8.8 and check at what hop the connection is failing ?

    Thank You!!

    hmm Text is not posting.

    Will Try again

    FYI The global Client was at 10.34.253.188

  • SaravananSaravanan Moderator

    Hi @Rage,

    Thanks for checking the suggestions and sharing the screenshots. We'll go ahead and perform packet capture on the SonicWall.

    Please follow below steps,

    • Navigate to INVESTIGATE | Packet Monitor.
    • Click on "Monitor Default" to clear out any previous capture parameters.
    • Click on "Configure"
    • In Settings Tab, disable all the check boxes.
    • Navigate to the "Monitor Filter" tab and specify the only fields as shown below,
    1. Ether type:   IP
    2. IP type:    ICMP
    3. Destination IP:   8.8.4.4
    4. Enable the checkbox “Enable Bidirectional address and port matching" and other check boxes should be left unchecked.
    • Navigate to "Display Filter" Tab, ensure all fields are empty and enable all check boxes.
    • Navigate to the "Advanced Monitor Filter" tab and enable all check boxes.
    • Click "OK" to save the parameters.
    • Click "Start Capture".
    • Click OK, and Start Capture.
    • Try to initiate the ping to 8.8.4.4 from the VPN client PC.
    • Please click on Refresh option in the packet monitor page to see the traffic.
    • Once the necessary packets are captured, click on "Stop Capture".

    Please check for dropped packets or packets not getting NATTED. Please share the screenshots here.

    Looks like it posted 3 times, My bad. (Sorry)

    Do you see anything in that capture that could help me?

    Maybe I need to do a capture with a different configuration?

    Hi @Rage ,

    The capture that you have pasted shows both the Echo Request and Echo Reply packets from 10.34.253.163 to 8.8.4.4 and vice-versa.

    I would request you to open a support ticket with us so we can guide you over the remote session and perform real-time troubleshooting.

    Thanks,

    Here is an attempt to ping google from within the Global VPN connection

    Odd That it appears to reply with the 2607:f8b0.... but not the ip 4 172.217.5.78..


    I monitored 172.217.5.78 instead of 8.8.4.4

    Also if I try to web browse it get cashed pages but no new page data.

    Maybe I need to change the packet monitoring settings.

    I am open to suggestion. (Worst case I learn something..)

  • shiprasahu93shiprasahu93 Moderator

    Hello @Rage,

    Based on the packet capture, it looks like the packets are being forwarded but there is no response. The NAT policy that you added specific to this traffic, do you see any statistics on it? Does it show any usage count or tx,rx bytes?

    Thanks!

    Thanks for the reply.

    "The NAT policy that you added specific to this traffic, do you see any statistics on it? Does it show any usage count or tx,rx bytes?"

    Which NAT policy should I be checking I don't see anything labeled VPN etc...

    I assume this will be in custom...

    Some of these are no longer in use..

    So I am going to go down the list and disable all with no traffic and see what happens.


  • RageRage Newbie ✭

    I was too slow to edit the previous post...

    I disabled or removed all nat policies with no traffic to clean it up...


  • shiprasahu93shiprasahu93 Moderator
    Hello @Rage ,
    I agree with @Nevyaditha. This NAT was suggested at the beginning of this post. I assumed you still had it.
    Could you please add it again and then test the connection?
    Thanks

  • RageRage Newbie ✭

    I have created the NAT policy with no improvement.



    I do have a question about Source IP (X1 IP), I assume I am correct to use the IP of the PPPOE connection.

    I used the IP of the PPPOE provided to the Sonicwall i.e. 10.70.2.15 (X1 Default Gateway)

    Should I be using the Public IP instead?



  • RageRage Newbie ✭

    I changed the X1 IP from My PPPOE connection IP to my public IP and it seems to be working. :)

    I need to test more but it looks good at this point..

    Thank you all for your time.

    I will post again if there is an issue.

  • shiprasahu93shiprasahu93 Moderator
    Hey @Rage ,
    Yes, it should be X1 IP. Although, it's PPPoE and might change, SonicWall should use that for NATting outbound traffic. You can see rule number 8 doing the same for your LAN traffic.
    Please monitor and see how it goes.
