My P-150 (FBSD 4.1) acts as a nat box and runs sendmail and pop server.
It's worked pretty good for a year or so, but now connections to the mail
server are SLOW. I don't think this is DNS related, dig's to the first few
nameservers in resolv.conf are quite snappy and web browsing through the nat
interface works well (still). So I'm a little stumped as to what could be
wrong, nothing has been changed, DNS is working, why is the mail server so
SLOW? I realize there is not a lot to chew on here, but just fishing for ideas,
has anyone out there had similar experiences and if so, what was the problem,
solution? Also, the syslogs show little or no load on the machine, the outside
interface is tied by 10BaseT to a cable modem, the inside interface is tied
to a wireless LAN via a second 10BaseT connection. As I said, all has been
working and still does, but Sendmail is SLOWed considerably, even a telnet 25
takes 30-40 seconds to get the welcome prompt. Any ideas would be helpful!
