Linksys Router E1200 Behind Sonic TZ670

My Tz670 has X0 Interface configured with 10.1.52.200 IP address SM 255.255.255.0. I created virtual sub interface with vlan ID 10 on X0 interface. I Configured IP address for this virtual interface as 10.1.53.1 255.255.255.0 and also configured the DHCP server for this interface range 10.1.53.2-10.1.53.254. Now I am pasting below the screenshot of my linksys E1200 IP address. Please guide me which IP addresses should I assign in Linksys router.

As you can see the first option is by default set as DHCP second option is IP address and the last

what should I do either static IP address should I configure. Second between Sonic and Linksys I have Cisco Switch. How linksys understand the Vlan ID

My Second Scenario I want my wireless users access Internet via connected to linksys wireless router. I am pasting my current lab diagram. Please guide

    configure the switch with VLAN 10

    set the uplink port to switch port mode trunk

    set the downlink on your Linksys port to

    switch port mode access

    switchport access vlan 10

    The Linksys then dosent need to understand the VLAN ID, the switch will add this on frames going to the firewall and remove the VLAN ID as it egresses to the Linksys

    Thanks Sir for valuable information. Sir I would like to discuss that I tried lab today as per second scenario. My Sonic Wall TZ670 X0 is configured with IP address 10.1.52.200 255.255.255.0 and DHCP is configured as 10.1.52.150-199. X0 is connected to a cisco switch 4948 and one of port of cisco switch connectecting Linksys E1200 Router with WAN Port of Linksys. I configured following IP addresses in Linksys as shown in following screenshot.

    as you can see for Internet IP I configured static IP as 10.1.52.100 in Linksys and defined a separate network for wireless clients which are connecting to Linksys, network I defined 10.1.53.X and also enabled DHCP in linksys. After this configuration I tried to connect my laptop I got an IP address from 10.1.53.X network as shown in following screenshot.

    and I tested to connect sonic wall. I got success as shown in following screenshot.

    After this configuration I am able to connect two different networks i.e 10.1.52.X and 10.1.53.X. I mean my laptop got an IP address 10.1.53.3 and accessing sonic wall 10.1.52.200 though ping. I also tested 8.8.8.8 though ping and got success but the issue is I am unable to browse the internet. I then followed some more steps in sonic I created an address object as shown in following screenshot.

    After this address object I created an access rule as shown in below Screenshot.

    I created in LAN to WAN zone also I tried the same rule in WLAN to WAN rule but I could not run the internet I was just be able to ping 8.8.8.8 and my laptop ethernet was showing you are connected to the internet. I also tried to test on my mobile the same result found. Please help me sir whats wrong in this regard. God bless you sir

    nothing wrong with what you have done but you've missed the fact that the sonicwall does not know about 10.1.53.0/24

    you need to add a route back to that network via the router at 10.1.52.100

    Can you please guide me sir how to add route in this regard.

  • MarkDMarkD Cybersecurity Overlord ✭✭✭

    Add a routing rule via the Policy section/Routing Rules

    Source Any

    Destination Cisco Linksys Network

    Service Any

    Nexthop

    Standard Route

    Interface X0

    gateway "the ip address object of the Linksys 10.1.52.100"

    metric 1
