I use FreeBSD 4.10-STABLE as a nat/firewall box. When connected to DSL, I got fast web surfing but many gaps in incoming audio traffic using some audio software. I switched to cable, and now audio works great, but at least when I pop open pages in Lynx right on the FreeBSD box, I often experience five-second delays--one at "202 OK" and one or more during the loading of the page. Tcpdump reports that I'm receiving incomplete packets, so I assume the five-second delays are timeouts on my box before a request for packet resends.
I'm afraid this is a black art of sorts, but in case there's a well-known solution, I'm all ears: Is there a fairly straight-forward way to track down and/or fix this kind of packet truncation issue? I don't know if the packets are getting truncated before they reach me or somehow on my box. More info on my topology: DSL was PPPoE straight into the fbsd box via a crossed Ethernet cable; the cable modem is connected via the same cable and uses DHCP. Fwiw, the NAT is served to Windows boxen from a second NIC in the fbsd box. The drivers for the two NICs are ed for the Internet side and dc for the local side. For PPPoE, I was using mpd. I use ipfw/natd for firewalling and NAT. I can surely provide more details to anyone who needs them. Please Cc me on replies (I hope this is not rude to ask; I'm just afraid of missing answers).
