I'm new here, but not in networking.
I have set the following on my Soekris 4801:
I can ping the outside from the serial console, including FQDNs; so
there is name resolution.
Media is 100baseTX <full-duplex>
I can use the webGUI from the LAN, so everything should be okay: reach
m0n0wall from the inside, and reach the outside from m0nowall.
But: No way to get to the outside from the LAN, everything times out,
ping, http, imap ... .
I have tried all, including unblocking 'private networks'.
I don't think I have to do any settings for NAT, I only want outgoing?
I rebooted a few times, including setting the outside to DHCP, and
everything is the same: all sides work independently, but no outgoing
traffic at all. The automatic NAT rule is
WAN 10.10.42.0/24 * *
and looks good to me.
Is this a bug? I ask, because I seem to be in good company:
"After numerous reboots it just seemed to start working!" seems a bad
way to debug this problem.
I have tried with 'Advanced outbound NAT' on and off, with proxy-ARP
because of becoming desperate; did a factory reset on the serial
console, and setting everything again (DHCP, see above).
Any hint appreciated,
