I am in the process of making a VPN config for use between two locations, but have run in to one problem i wonder about whether it's fixable.
On the Cisco 831 I use, I have made port forwardings for a number of services, among which are port 80, 443 (webmail), 25 (smtp) etc. All this works fine.
However, when you connect to the 831 using VPN, its not possible to get to the server I use for webmail/smtp etc because apparently the port forwarding rule somehow blocks this? When I remove port forwarding and try to connect while on the VPN, everything works, but then the external connection is of course down :-(
Is there any way to have the port forwarding, but also have the same servers reachable under the same port number while on the VPN?
