Site to site VPN from ASA 5510 to SG720 works in one direction.

[jainyc]

I'm an newbie to the world of Cisco and I used the VPN configuration wizard to create a site to site VPN between a Cisco ASA 5510 and a secure computing SG720. The tunnel works. I can ping and access resourced from the Cisco side to to the network behind the SG720 but it does not work the other way around. I thought that since the tunnel is bidirectional it would work in both directions. I know there must be something simple I'm missing.

I've included the config below and I've removed some oft the IP addresses.

The local network is 192.168.60.0
The remote network behind the SG720 is 192.168.10.0

Thanks in advance.

Hi there. Your cisco side config is correct, in that you have defined the access list for the crypto map..which includes an IP allow from the Cisco side to the SG720 side.

My guess would be that you need to create some form of access list entry in the SG720 to allow from local to remote subnet.
