Configuring Cisco 877 to allow connections to an ISA VPN behind it
Posted on 2011-05-06
We had an ISA server supporting PPTP VPN. The ISA server was behind a Linksys router, in which I had configured DMZ setting to refer to ISA IP address in order to allow VPN remote users to connect.
Now, we have replace the Linksys with Cisco 877. Thanks for EE members help in configuring it.
Now the final step is to allow ISA VPN remote access. I think it need some config for GRE and PPTP protocols Natting.
Would you please help? The ISA server address is 192.168.1.45
