Accessing internet via IPSEC LAN to LAN set up using Cisco Routers

[alexals]

Hello experts !

I would like to get some idea or pointer about accessing internet via IPSEC LAN to LAN set up using routers. My IPSEC LAN to LAN set up works as expected but I'm wondering if it is possible Site B's LAN able to access internet via Site A's LAN ? I would like to have Site B's LAN able to access internet via IPSEC LAN to LAN set up just like Site A's LAN. If it is possible ... How does the IP routing looks like !

Thank you very much in advance to you all.

Hi,
What type of VPN do you already have configured? Crypto Map or VTI (DMVPN/FlexVPN)?

If you are using a Crypto Map you would modify the Crypto Map ACL to include "any" network to route internet traffic over the tunnel.

If you were using DMVPN/FlexVPN you could just advertise 0.0.0.0 route over the tunnel interface. You should define a Frontdoor VRF on the outside/external interface and use the global routing table for internal network.
