I am currently trying to setup a GRE tunnel on a cisco 861. As part of a configuration template provide by an outside source I am recommended to use a sub-interface on the router but the recommended configuration does not work.
Recommended configuration (IP's removed for security):
ip address 10.x.x.x 255.255.255.0
no cdp enable
ip address 109.x.x.x 255.255.255.0
crypto map cmevpn
ip access-group 199 in
Fa4 is the WAN interface, /0 is suppose to be the tunnel, /1 is the normal internet connection
Can anyone explain why it doesn't work and how best to get a working solution
