Vpn with no encryption

[ggdde]

Is it possible to create a LAN to LAN VPN using 2 Cisco 827 connected to internet with fixed IP using only a tunnel interface ? I don't want to use encryption.

The IOS is IP only rel 12.x.x and the lan use private IP. ANyOne has a configuration sample ?

Thank for suggestion

I guess you could use AH only (and not ESP transforms ) within IPSEC. You could even use esp-null as an option when defining your crypto transform sets.

Need to look at

the VPN configuration manual that you should have.

Otherwise contact your A.M if you dont.

Yes, it's possible. If you create a GRE tunnel interface using the outside IP addresses of your routers, then you will have a tunnel without any encryption (and protection of the data).
