We have a Virgor 2830 router that has IPsec connection to one location using MD5 DES G1 with one subnet and from the same router we have an IPsec connection MD5 DES G2 with 4 subnets connecting to a different firewall.

When the multiple subnet (second one) VPN is online working fine, we then enable the VPN with the single subnet. The Virgor router reboots time and time again.

Any ideas people?

Hi
Are they multiple SAs at each end? If so have you ticked the box that says "create separate SA for Each Subnet"?

Hi,

The VPN with multiple subnets has the tick box selected and all works fine with this tunnel. When we enable the VPN tunnel with a single subnet along with the other VPN tunnel the box reboots.
