RV082V3 versus RV082V2 vpn with a central CISCO 2611XM


We have up un running the following configuration:

10 x RV082v2 small business routers and one central Cisco 2611XM

with CISCO AIM-VPN/BP VPN module. They are all 10 functionig properly

with the attached rv082v2 configuration:

When adding a RV082V3 box to the network, with exactly the same

configuration, it fails in the DPD (Dead Peer Detection) phase

with the following error messages in the RV082 logs:

Dead Peer Detection (RFC 3706) enabled

VPN Log    (g2gips0) #117: sent QI2, IPsec SA established {ESP=>0x30c1cfe5 <0x3ce0388f

VPN Log    (g2gips0) #116: DPD: R_U_THERE_ACK has invalid icookie

VPN Log    (g2gips0) #116: DPD: R_U_THERE_ACK has invalid icookie

VPN Log    (g2gips0) #116: sending encrypted notification INVALID_COOKIE to A.B.C.D:500

VPN Log    (g2gips0) #116: received Delete SA payload: deleting ISAKMP State #116

I looked through all your discussion lists and I had no answer. It seems to

be a parameter mismatch between the central 2611XM and the new RV082V3 box.

We used several versions of firmware with no success (v4.1.0.02-tm, v4.0.0.07-tm).

Please advice us what to change such as to bypass this error or where

to look. If there is an incopatibility in the new firmware please let

us know such as not to loose more time on this issue.

Thank you in advance

Best Regards
