WRVS4400N VPN Connectivity issue

Hi -

I have 2 WRVS4400N's installed in our network, one at each end of a VPN tunnel between 2 physical locations.  I continue to have issues with the VPN to "Stay" connected, even after purchasing another new WRVS4400N 4 months ago.  I can reboot both routers, and the VPN connects with no problem, but hangs up after a few hours / days (no pattern). 

I am taking a hard look at the issue now, as about 1 month ago, the newest router "automagically" reset it itself back to factory settings (thus interrupting nearly everything in our network).  After contacting support, we reset the router and re-configured it to our environment.  It is plugged into a surge protected UPS (yep, I thought maybe a power issue caused the problem, but it's not).  Then about 1 week ago, the other/older (9 month old) router lost it's configuration.  again, reset it and all works.  Including the VPN, but the VPN still works as it did before.... connects for a while, but then drops and generally I need to reboot the router to get it connected again (clicking on the Connect on either router doesn't work until after a reboot).

Also, in light of the recent "lost configurations", I turned on logging and now I'm getting TONS of emails of log activity, even when the network is idle (no users, no background jobs running).  Yep, this sounds great, but I dont' know how to read the messages (there in english, but don't make any sense to me).

after rebooting and no inter activity, I get this kind of log, all night long (to me it generally looks like the VPN connection resets and increments by 1... I'm taking a guess that the increment hits a limit someplace and I lose my VPN).

also, I get this log quite often, but have no clue what it means, or if I should be concerned (but generally when the network is in use, but not neccessarily the VPN connection)

:

Dec  8 04:09:38  - klips_debug:pfkey_acquire: no sockets registered for SAtype=ESP).

also, I get this log often on one of the routers, but not so much on the other (and have no idea what this is):

Nov 27 00:22:22  - hit KRIS_DDOS_TYPE

Nov 27 00:25:26  - hit KRIS_DDOS_TYPE

thanks guys,

Brian

WRVS4400N VPN Connectivity issue

I have this same issue. I also tried creating continuous traffic across the vpns via ping /t but no dice. The logs are not helpful for me either. Any ideas?

WRVS4400N VPN Connectivity issue

This entry is for IPS

Nov 27 00:25:26  - hit KRIS_DDOS_TYPE

Most of the other entries are VPN exchanges. You can disable the IPS to lighten the router load.

Can you post screenshot of both VPN configurations?

I have actually tried this as well and the connections still go down at random.

Re: WRVS4400N VPN Connectivity issue

Both of these vpn's terminate to a sonicwall. One is the sonicwall at corp HQ and one at HR HQ. These sonicwalls are also linked to each other via a static vpn route. The keys are set i just removed them for security.
