FVS318Gv1 connected to a FVS318Gv2
Hello. I have a question about the two models in the subject. My network was so composed: Net A) One FVS318G directly connected to Internet with static IP. Local lan IP 192.127.0.0/24 It was u...
What are you using for the ike and vpn profiles in terms of md5/des, etc? Set each one to the lower possible setting on both routers and see what happens. Disable all dpd on both sides for now. Let's see if we can get the tunnel up and then increase security until it breaks again.
No effect :(

I have decreased the security to basic MD5 and DES encryption. The tunnel has gone up and now I am able to ping the PCs on both sides. So far this trick seems to work fine :)
I only don't figure out how is it possible. When the old router on Net A broke down I tested the new one in my lab connecting the two with success. Only when I deployed the new router in his rack I started to have problems. Maybe there are some provider's network devices which block or corrupt VPN traffic. Who knows :-/So far thank you very much!!
Glad you got it working. :) You can try upping to 3des and other settings now that you got it working. If it breaks, you can change the setting back to what it was previously and everything should still work.
I've seen all sorts of strange things like this before, especially between different brands of equipment. Seems that even though IPsec tunnels are a standard, they are poorly tested for inter vendor operability.
Strangest one for me is one tunnel I have that works fine until it stops working. Only rebooting the cable modem that is on its wan fixes the problem. And here's the kicker--we have another cable modem from the same provider that doesn't have this problem (it's also connected to the same router). The only thing I've figured out on this one is the modem manufacturer has some sort of issue since it only happens after weeks (even months) of uptime. But the cable company won't change the modem or acknowledge there's a problem. :/ Ahh, the joys of IT work...
