I'm not sure this is even a router issue but have a problem with a site to site tunnel created on our FW.
The circuit in question delivered by ISP to our 3640. Router to FW vai FA0/1 which is assigned our global IP 66.52.5.x
The tunnel is setup with a client through our Sonicwall and inidcates that it's up with end to end connectivity. The problem is, we cannot pass traffic.
If I trace from the segment of our internal network which will use this tunnel, it hits our global ip the the 3640 router and dies (66.52.5.x).
According to Sonicwall, there should be no need to NAT on the router or do anything for that matter because the FW will handle everything through the VPN configuration.
So the million dollar question is why does this tunnel show green yet packets hit the router and die on the way out.
Like I said, not sure of this is even a router issue but it appears it maybe since the FW shows the tunnel up but yet no traffic can get past the router. Any thoughts on this would be greatly appreciated.
Thanks in advance
