I am attempting to get a point to point GRE tunnel set up for backup internet access. Here is some backgorund information on what I am trying to do (if it is even possible):
We have a server co-location what will let us use their internet POP for a backup internet solution from our Corp HQ via fiber. Both locations are physically seperated. What I want to do is create a point to point tunnel that will start at the co-location and terminate on an interface on a UTM firewall device at HQ. So far I have not had much luck getting this to work. Here are the tunnel and route configurations from both sides:
CORP HQ:
interface Tunnel1
description Tunnel to Tierpoint for Internet
ip address 10.0.0.5 255.255.255.252
keepalive 5 4
tunnel source 10.92.0.2 <-- IP address of the UTM firewall
tunnel destination 66.45.*.* <-- IP of the outside address at the co-location
interface Loopback1
ip address 10.0.0.1 255.255.255.255
interface Vlan92
description Backup Internet
ip address 10.92.0.1 255.255.255.248
ip route 66.45.*.* 255.255.255.255 172.16.6.242 <-- Next hop address at the co-location
CO-LOCATION:
interface Tunnel1
description Tunnel to Corp for Internet
ip address 10.0.0.6 255.255.255.252
keepalive 5 4
tunnel source 66.45.*.* <-- Outside internet address
tunnel destination 10.92.0.2 <-- Ip on the UTM firewall
interface Loopback1
ip address 10.0.0.2 255.255.255.255
interface Vlan2
ip address 66.45.*.* 255.255.255.224 <-- Outside internet IP interface
ip route 0.0.0.0 0.0.0.0 66.45.170.193 <-- Next hop IP for the default route
ip route 10.92.0.0 255.255.255.248 172.16.6.241 <-- Next hop IP at HQ
if there is a way to get this to work, I would really appreciate any help. If there is a better way than this, I am all ears!
Thanks!
