I use 2651XM as gateway. We have a sister concern. It also uses 2651XM as gateway. I have created a GRE tunnel between our office (Branch A) and the sister concern (Branch B). users VPN to Branch A. Recently a user asked me if he could access the resources on Branch B while VPNd to Branch A. Branch A and Branch B have different IP subnets. Could you please guide me as to how the routing will happen? How would NAT affect this?
Branch A needs to know Branch B subnets via the GRE tunnel if it's the only link between them either via static or dynamic routing protocols. Then Branch B needs to know the user internal IP address from the GRE tunnel.
If the GRE tunnel is not configured on the 2651XM, you need routing protocol as well between those two routers.
I expect the user is already using Branch A VPN gateway as his default-gateway so nothing to change here.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
