Broken switch? *sigh* I've got (they've died off lately, but were much more frequent when I first implemented the BSD-based NAT box) the same sort of error here with the following setup: +---------------+ LAN1--| Catalyst 1900 | +---------------+ +-------------+ +---------------+ LAN2--| Catalyst 1900 |--| FreeBSD 3.0 |--| Catalyst 2940 |--INET +---------------+ +-------------+ +---------------+ LAN3--| Catalyst 1900 | | Catalyst 1900 | +---------------+ +---------------+ The Catalyst 1900's on the left provide 10BT connectivity to three local nets (10.0.1, 10.0.2, 10.0.3) and connect to the BSD box via 100BT. They are daisey-chained via standard cross over cables using their 100BT uplink ports. LAN's 1-3 and Windows 95, Windows NT and Macintosh LANs. They undergo packet filtering and NAT at the BSD box. The Catalyst 2940 and 1900 switches on the right provide 100BT and 10BT connectivity (repsectively) for servers I have 'outside' of my firewall (FreeBSD shell, FTP, personal WWW, etc. servers). Just FYI, maybe my setup will be similar to his in some way and present an obvious design flaw.
