I have an Adtran NetVanta 3448 and a Sonicwall NSA 3500 that at long last I have established a site-to-site IKE/IPSec VPN connection over. The tunnel shows as up from both ends.
From Site A (SonicWall), I can contact Site B (Adtran). I can NOT Contact Site A from Site B. Here's a quick look at how I'm set up:
- Site A - 10.0.0.0 / 255.255.0.0 (LAN) --> X.X.131.90 (WAN)
- Site B - 10.10.0.0 / 255.255.0.0 (LAN) --> X.X.58.218 (WAN)
Upon running a packet inspection from the SonicWall (Site A), it is showing that the packets from X.X.58.218 (Site B WAN) are being CONSUMED rather than FORWARDED.
Can anyone help to point me in the right direction on what might be causing traffic to only flow one way?
