VPN ISSUE: Sonicwall NSA 2600 to Cisco RV110W


I am currently trying to establish a tunnel between a Sonicwall NSA 2600 and a Cisco RV110W. Phase 1 completes fine, and it shows as established on the Cisco device, however no data will be transferred. On the Sonicwall two errors appear, one is that the networks do not match and the other is that the Phase 2 did not work. I have posted pics of each configuration below with the public IPs removed, as well as the logs from the Sonicwall. Any help would be appreciated!

On your Sonic Wall you are using DH Group 2. On your RV180W, you appear to be using DH Group 1.

Make sure the Phase 1 settings are consistent with Phase 2 and then are exactly mirrored on the other end.

You may need to enable NAT Traversal as well.
James SeifertAuthor Commented:
The DH Group 1 on the Cisco is for the PFS, which is not enabled, so that setting does not apply currently. I have it disabled on both ends, should PFS be enabled?

I will go ahead and try the NAT Traversal setting and see what happens.

Thank you!

I leave PFS OFF .  I use a Cisco RV220W and do not see the superfluous setting there.

Double check both sites for the Phase settings and the pre-shared key as you say Phase 2 does not connect.
