Hi,
I've three sites inter-connected by MPLS and running GRE tunnel between them. Only site A has internet connection, i.e. site B & C connect to internet via router A. Now when site B & C connected to internet, the packet stopped at site A internal interface (10.10.2.1). Can anyone tell me is there specific configuration on site A internal interface to allow site B & C access internet via router A and what's missing in below configuration ?
Internet | (202100.20.x) Router A (10.10.2.x) | ISP router | | Router B Router C (10.10.3.x) (10.10.4.x)
Router A Interface s0/0 ip address 200.100.20.2 255.255.255.252 ip nat outside
Interface f0/0 ip address 10.10.2.1 255.255.255.252 ip nat inside ip route 0.0.0.0 0.0.0.0 200.100.20.1 ip nat inside source list NATIP interface S0/0 overload
ip access-list extended NATIP permit ip 10.0.0.0 0.255.255.255 any
Router B Interface f0/0 ip address 10.10.3.2 255.255.255.252 ip route 0.0.0.0 0.0.0.0 10.10.3.1
Router C Interface f0/0 ip address 10.10.4.2 255.255.255.252 ip route 0.0.0.0 0.0.0.0 10.10.4.1
thanks
