I have a GRE tunnel over an ipsec VPN which for the most part works fine, however I have 1 subnet that can not be reached.
The destination address of the GRE tunnel is 172.16.250.25.
Also on the 172.16.250.0 subnet I have other devices that I need to connect to.
I have a static route ip route 172.16.250.0 255.255.255.0 Ethernet0/0.
The Ethernet0/0 interface has a connection to a managed router, and is using a public address.
I can get to several other subnets in my network, but can not get to this 1 subnet.
