Subnet Mask mismatch with Cisco and Nortel

Hi,

I am trying to setup a IPSec VPN tunnel between Cisco 3030 concentrator and Nortel Contivity 5000.

When both sides configured with /24 subnet mask in its respective network list / intresting traffic list the tunnel is build but there is no communication between servers. But if the intresting traffic is configured on /16 subnet mask the servers communicate with each other.

Please anyone if aware of this let me know.

Appreciate your time.

Regards,

Amol M.

Re: Subnet Mask mismatch with Cisco and Nortel

Hi,

When the tunnel is built on the /24, do you see packets being encrypted and decrypted?
