VPN Problems after network gateway changes.
Posted on 2008-06-24
I have users coming in to my network on a ipsec vpn through a Cisco ASA 5510. They have access to one server (mail server) and use a virtual address range of 172.16 etc. The mail server gateway setting is pointing at the asa box on ip 254. We also have a router going to our head office on ip 1.
Now our head office wanted us to route all mail in and out to the head office so asked us to change the gateway settings on the mail servers network card to the .1 router instead of the .254 ASA box. All is fine except the vpn users can access the mail server , cant even ping it. So i put the gateway back to 254 and then added an extra gateway (under adv settings) for .1 which works fine.
Problem is any time i restart the mail server the vpn users are locked out again until i remove the gateway setting and put them in again. Any Ideas?
