Could be a problem related to path MTU.
If the connection seems to stall, try to lower client's interface MTU ( ie.
to 1000 ) and retry; if it works, maybe somewhere on the path ICMP error
messages got filtered (ie. "Frag required but DF set").
Otherwise, you need to diagnose the problem at a lower level ( ie. Tcpdump
plus some packet generator).

Oggetto: [m0n0wall] Unreachable website, m0n0wall problem
Since I have installed m0n0wall I have not been able to get on
www.newzbin.com. I have spent several days trying to figure it out, have
accused my provider of blocking the host ;-), but nothing has worked up
I have cable and the admin at my provider (same network) can open the site
without problems. I have done traceroutes from both Windows and Linux and
they all stop at some host in the UK (hop16 117 ms 126 ms 173 ms
I have upgraded to the Beta (1.1b16), downgraded back to 1.0, completely
emptied my config file and started over. Even with the most basic config, I
am not able to get through.
However, as soon as I hook up my old Linksys router instead of m0n0, I can
get to it.
I an sure it happens with other sites as well, but at first I did not pay
much attention to it. Some sites are down, that's life. But when I found out
that NewzBin was not down and that I could get there from any other location
but my house, I started troubleshooting with this site.
I am running m0n0wall on a Soekris net4801, my clients are W2K, WXP and
Has anybody encountered this problem before? Or something similar?
Thanks in advance,
For your info, here's my minimal config-file:
