VPN s2s Issues

david-lima

Hi all,

I have two cisco ASA used to connect two offices.

In the main office I have a HTTP server and SMTP server.

In the remote office I have two Vlans (vlan 1 and vlan 90).

Both remote vlans can ping to the HTTP and SMTP server, only the VLAN 1 can access to the HTTP and SMTP service, but, the VLAN 90 can access to these services.

I think is some configuration in the ASA, please give me an advice.

Best regards.

David

Hi,

Would really need to see some configurations to see what the problem could be.

Since there is somekind of connectivity between the servers and the 2 LAN network it would sound like a problem with some VPN Filter or Interface ACL or perhaps something on the actual servers blocking the connections.

Hi Jouni, thanks for your reply. This is the config of the remote site:

The network 10.2.9.0 can reach all services of the main office.

The network 10.2.90.X /91.X/92.X/93.X can ping all the servers of tha main office, but cannot access the HTTP and SMTP services.

name 10.2.0.10 smtp.pro-mujer.org
