Duplex mismatch slowing down my network

pava_rulez

Hi everybody,
I've got troubles with our lan at work; our external firewall server (Cassiopea) blaims about a duplex mismatch. Using mii-tool on this server returns

Can you show a sample of you network as a drawing ?
and also run mii-tool with more verbose output like
mii-tool -vv

OK, you can find the scheme in here. Hope it works...

1 further thing:
10.0.0.1,2,3 are servers' NIC addresses onto DMZ

The only one that look off is Gate1's eth0 10/hd every thing else on that hub is 100/hd
so I'd check that NIC and cable.

ps I'd still like to see the mii-tool -vv output just do dubbel check the links capabilities at both ends

If you have the resoucers I'd replace Gate1 eth0 with a 100m card and then the Hub with a 10/100 switch next.

To be honest I've forgotten to mention a couple of things. My hub has two 100Mb ports and some others (I can't remember how many...) 10 Mb. When I started the post I had Cassiopea and Orione attached to 100 Mb ports and Gate 1 attached to 10 Mb one. Now I've replaced Gate1's DMZ attached Nic with a 100 Mb card, but cable is still plugged into 10 Mb port. Can use a 10/100 switch that I've just purchased which have 5 10/100 Mb ports? And have I to configure it in some special way or can I simply plug the cables into it and everything will work?
Thanks

No way, I can't use switch 10/100 anymore, but a Fast Ethernet Hub.
I've plugged all of the cables in 100 Mb ports and set every nic to HD-100Mb. But here's the result...

around 2ms to the first hop in internet is SLOW? Man... i'm more used to have 20-50ms for that...

about the stars i'd bet on firewall settings which don't allow traceroute responses to be send out onto that subnet.
