hello,
i got some problems..
i had natd, sendmail, and qpopper running on 10.1.5 just fine
untill i setup dyndns for it. the only problem that has occured since is
that when the other computer that i'm sharing an internet connection
with gets a server time out error when checking/sending email with outside email accounts(ones not on the server i'm running, like yahoo, etc.).
it does however, find the server + authenticate the user,
but then it will just time out.
heres how i have the connection setup.. let me know if you need more info.

computer1 - the osx box:
has 2 nics,
en0 connects to the second computer
en2 connects to the dsl modem (PPPoE)

ifconfig aliases them as follows:
ppp0 - is whatever my isp gives me at the time
en0 - 192.168.0.1
en2 - 192.168.0.1

natd starts up like so:
natd -dynamic -interface ppp0

ipfw rules look like so, wide open:
00100 divert 8668 ip from any to any via ppp0
00200 divert 8668 ip from any to any via en0
00300 divert 8668 ip from any to any via en2
00400 allow ip from any to any
65535 allow ip from any to any

computer2 - pc running XP(my parents machine):
ip -192.168.0.3
subnet- 255.255.255.0
gateway- 192.168.0.1

as i said, everything worked fine before. but as soon as i setup dyndns it went all loopy and times out everytime it tries to send/retrieve email. but it does find the server, it does authenticate, but then it just times out..
i'm really lost and i'm not sure that natd, smtp or pop3 have anything to do with it. the really strange part in my mind, is that even when you go to the yahoo account using the browser based interface on yahoo it will still time out..


thanks a lot to anyone who may be able to help, or even just point me in the
right direction...
thnks,
mmm.......a-YESS!!
