Yes, you're inbound traffic is not going to make it back out with the other gateway being set. When we had to change our complete class C, we handled the delay in DNS for our websites by setting up a Apache webserver for old IPs with redirects to the new corresponding IP address.
Then we added bonded T1's to our single T1, and ended up going with BGP so that we could use the bonded T1's as our primary bandwidth and the single T1 is now failover. -----Original Message----- From: Chris Green [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 18, 2005 1:31 PM To: 'Dan Swartzendruber' Cc: [email protected] Subject: RE: [gb-users] Two EXT interfaces for transitioning ISP's I understand that, but if I could BGP I wouldn't be asking about the firewall. ;) This is a Business DSL line with 4 IP's we are leaving for a bonded T1 setup with 16. There is no way to do this at a router. I'll tinker with the gnatbox and give it a shot with two EXT interfaces to see what happens.

Is this not the case here? It might be, my question was why you thought that would not work properly. Most BGP routing at multihomed providers is asymmetric. ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/ ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/
