NAT on Router running BGP

[acollard83]

I am trying to get NAT working on a router that is running bgp. We are trying to nat against our publicly announced space vs one of the peers/providers ip address. I've tried using a loopback interface and a sub-interface, neither worked. This is on a 7206VXR with an NPE-G1.

sh run

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.

Sorry. Relevant config below. BGP Peers are on GI0/1 and GI0/3. I am trying to bring the inter-vlan routing on to a couple c3560's and get rid of an old sonicwall.

interface Loopback3
ip address 162.210.240.x 255.255.255.248
ip nat outside
ip virtual-reassembly in

interface GigabitEthernet0/2.66
encapsulation dot1Q 66
ip address 10.1.11.1 255.255.255.0
ip nat inside
ip virtual-reassembly in

ip nat inside source list 50 interface Loopback3 overload
access-list 50 permit 10.1.11.0 0.0.0.255

how are you advertising the route through BGP ?
you dont need to have an interface to nat .. if you own the segment, pick an ip address and instead of the interface command actually use the IP address ..
your router should respond with arps when queried of "who has xxxx"

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.

That works. I just used NAT pool.
