Brian,
Yes, you provided me with just enough clues to track down the problem.
Since posting a reply earlier this morning I have been able to sit down
once again this evening and look at the:
net.inet.ip.forwarding: 0
response I obtained.
Looking at the docs once again I realise that ip forwarding should be
set=1 by the:
gateway_enable="YES"
flag in /etc/rc.conf and that this is picked up at boot time.
I discovered a mailing just today from Marcel Moolenar <marcel@scc.nl>
where he gives:
sysctl -w net.inet.ipforwarding=1
I tried this and everything now appears to work OK. I can ping,
traceroute, receive web content from the windows clients. I cannot tell
you how happy I am to get this working.
What I do not understand is that I have ``gateway_enable="YES"'' in my
rc.conf file. It's been there from the date I started configuring
FreeBSD as a gateway.
I am beginning to wonder if some of the other settings are interfering
with the gateway option. I have attached the (quite small) rc.conf file.
If anyone can spot any obvious no-no's in the file, please let me know.
Can I thank you Brian, Marcel, Matthias Teege, Todd Backman, Jason
Wells, Steve Doty, Jeroen Ruigrok, Doug@gorean.org (and anyone else I've
not included in the list) for sticking by this one and helping a
newcomer out.
End of thread?
