Anyone got any clues? This sounds a lot like your cable modem provider throtteling the link if it doesn't see some sort of negotiation (DHCP, ARP, etc.) after a fixed amount of time. I could imagine that some companies do this for residential connections. Does your cable modem provide IP service, or do you need PPPoE or something like that? > Mike D wrote: >> I have a set up where my FreeBSD 4.4 box is acting as a firewall >> and gateway between a cable modem on xl1 and my home net on xl0. ... >> It seems that after approx 10 hours the connection REALLY slows >> down, most connection attempts on other ports (e.g. 110) time out >> and I have to reboot the box.
