Ah! And here lies the crux of it. If you have Microsoft Proxy server
installed with Proxy client on each of the machines, the Proxy client
hooks into the IP stack of the client machine. I've never looked into it
in any depth, but this may be what is causing your headaches.

The solution is either to set up the proxy server to proxy HTTP
properly, install a different Proxy software on there (try Wingate), or
alternatively, install FreeBSD and squid on there. :)

Cheers,
Aled.

 Not really that strange a routing situation, and definitely pretty easy,
 here's one possible way:
[SNIP solution]

Just wondering...

..I've had to play with bridging recently because I'm playing with
protocols that have IP's embedded in them, so I can't use NAT - would it
be possible (though probably somewhat more complicated) to bridge the
two ethernet interfaces together and NAT the third interface to an
overloaded IP A?

That way you get around needing to NAT the servers (which in my case I
couldn't do anyway).

Cheers,
Aled.

 Is the system configured to forward packets? Assuming that 5.x has the
 following variables available (I still run 4.8 here), try:
 
 sysctl -a |grep forwarding
 
 You should see net.inet.ip.forwarding: 1. If it's 0, then your
system
 won't pass traffic between the the interfaces.

You're right, it won't. *sigh* But it does now.

Thanks for that. I can't believe I missed that one out. There ends a
weekend of pissing around (all hardware sucks). :)

Now to see if I can trim down my ruleset a little bit.

Cheers,
Aled.

no response on unnumbered bridged interface?

2003-09-01 Thread Aled Treharne
Hi guys.

I've just upgraded (aka reinstalled) my firewall up to 5.1-RELEASE. The
hardware isn't particularly new, but it's been quite happily trudging
along for the past few years using 4.something. However, with 5.1, I've
found weirdness and I wanted to check to see if this is expected
behaviour or not.

The machine has two 3C509's ep0 (external) and ep1 (internal). Ep0 is
numbered and the following sysctl variables set:

Net.link.ether.bridge_cfg=ep0,ep1
Net.link.ether.bridge_ipfw=1
Net.link.ether.bridge=1

Now it bridges quite happily ( I have IPFIREWALL_DEFAULT_ACCEPT set in
the kernel), and I can ping back and forth without any problem. However,
if I try and access the bridge from a machine connected to the switch on
the inside interface, it doesn't respond. Tcdump on the box shows ECHO
request packets, I see arp traffic (and the inside machine has the
correct mac address), but I see no echo responses. This is a problem,
since I'd like to admin this box from inside my network. :) I also
wouldn't mind the box seeing the internal network...

I can't see anything wrong with what I've got, and there's nothing in
the docs about this problem. I also experienced this problem with a
Intel EtherExpress Pro I had in there as the internal interface, and
both the ep1 card and the Intel NIC have worked in other boxes.

Has anyone got any ideas on what's going on here? As far as I can tell,
the config is identical to my previous installation...

Cheers,
Aled.
