ISP forwarding WAN IP
Hello Everyone,
I hope that everyone's doing well.
I'm having some issues with the way the ISP is giving my client their WAN IP.
We've a Tz 370 connecting the X1 (WAN) to their device, for this connection to work, I need to use some IPs that they gave me, lets say that these IPs are:
For my sonicwall: 10.0.0.1
Their device: 10.0.0.2
And then they're forwarding our WAN IP to 10.0.0.1 which is the IP that we've configured on our WAN port.
The issue with this is that we've IPSec connections, and our WAN port should have the outside WAN IP, not the 10.0.0.1.
To work this out, what I did was:
On the X1 port I've configured the WAN IP
After that, I went to the ARP table and created on the X1 port the IP 10.0.0.1 and ticked "publised".
Also, I added the 10.0.0.2 IP with the MAC address from my ISP device to the X1 port in the ARP table.
After all this, I went to the routing page, and created a route:
This works ok for a while, after some time, and it really depends, can be 1 hour to 4 hours or even 6 hours.
The connection to the internet stops working.
I used the packet capture, and the ARP requests from 10.0.0.2 (ISP device) are being dropped.
Any one can help me with this one?
