LAN2LAN between ASA and Cisco 2821

iholdings · ‎03-09-2007

Greetings,

Users on remote network behind Cisco 2821 reporting dropped connections to mail server behind ASA. 20-seconds later, the connections get re-established. I run a constant "ping" to the remote LAN and do not see a drop over the tunnel.

Any ideas?

Thanks.

Try enabling "inspect esmtp" to see if that helps.

Thanks for the quick reply.

As I understand what I've read - esmtp inspect is on by default on the ASA. Is that true? So - in this case - would I turn it on in the router as well? BTW: These two sites are on a LAN2LAN VPN .... does that change what you suggested?

Thanks.

Hi,

If you are running 7.2.2, try disabling the inspect esmtp on the ASA rather than enabling on the router.

HTH,

Please rate if helps,
