In preparation for a new ISP connection I have setup a router to ensure connectivity to our new ISP. The routers are working the BGP session established and the default route delivered from the ISP.
Now, what I'm trying to do is take the router behind a CheckPoint (R70.3 on SPLAT) and establish the BGP session. I am using Network Adress Translation on the firewall to tanslate the internal router address to the expected neighbor address the ISP is expecting.
I can ping from the internal router to the External gateway and the BGP Neighbor. However the BGP session will not establish. I see a BGP request go out and also request come in from the ISP's router but it does not establish.
When it was working ie testing from a router externally I hade the ebgp-multihop to 2 I am assuming this would stay the same internally.
Any pointers would be greatly appreciated.
