We have aquired a client that already has a site to site VPN between 2 existing TZ180's which is working fine (lets call these sites A and B). They had already sourced a Sonicwall TZ100 to put at a new site C. I have installed the Sonicwall TZ100 at site C but am struggling to get a site to site VPN working. They only really need the site C to be able to get to site A and vice versa. I normally use Watchguard, Draytek and Cisco so using Sonicwall is a first for me.
OK details so far:-
Site A - Sonicwall TZ180 SonicOS Standard 184.108.40.206-27s
Site B - Sonicwall TZ180 SonicOS Standard 220.127.116.11-27s
Site C - Sonicwall TZ100 SonicOS Enhanced 18.104.22.168-52o
I have setup the VPN policy between site A and c but I get the following error in the log:-
Site A Log = IKE Initiator: No response - remote party timeout [External IP of Site A], 500 [EXTERNAL IP of SIte B], 500
Anyone had any experience of setting up a site to site vpn of these two models? There appears to be no IKE settings in the TZ180 to set unlike in the TZ100 where the Local and Peer ID can be set. I have tried both main mode and aggressive mode. Any ideas?
