I recently moved my home firewall from an old B56 box (Gateway 400Mhz, 512 MB, iprb external NIC, rge0 internal NIC) with no changes to tcp settings via ndd to a B64 box (AMD 64 3200+, 2GB RAM iprb external NIC, rge internal) also no changes to tcp settings.
To complicate matters, I was forced to upgrade an old Cayman 3220H router to a Netopia 3346N. Once I switched to the Netopia, I noticed while snooping the external interface, a few ICMP Destination unreachable messages. I was able to ping and eventually connect to the site that was showing unreachable. It wasn't noticeable to users with the B56 firewall. but with B64 and B65, tcp connections frequently stall, and it takes a few attempts with firefox to establish the connection. OpenSolaris.org is one of the sites that exhibits this behavior along with msnbc.com. I've set the MTU to 1462 on the external interface and disabled path MTU discovery, with no success. I'm stumped. What's changed between B56 and B64+ to cause this behavior? This message posted from opensolaris.org _______________________________________________ networking-discuss mailing list [email protected]
