procurve 2424 vlan and bridge

I have a setup with a 2424m that have 2 vlans and a bridge between them, what accours is that i get a packetloss from 30% to 70%.

My setup is as follows:
vlan 1 consists of port 1, 7 and 8.
vlan 2 consists of the rest.
(None of these vlans are the default 1)

I have my internet connection on port 1, and on port 7 i have my bridge (transparent firewall running linux) wich is connected to the other vlan.

internet > vlan1 > bridge > vlan2 = packetloss

Everything works like a charm if i do like this:
internet > another switch > bridge > vlan2
so it shouldn't be the bridge making the fuss.

stp not enabled, no trunking.

Any ideas?

What do the port counters look like on ports connected to the bridge? Do you have a full/half duplex mis-configuration on either of these ports?

Thanks for your reply.

port counters look normal. no Errors Rx, no Drops Tx.

I tried every setting possible concearning half/full duplex.

The internet is distributed from another procurve with 10baseT-FD, and that is what Port status on my switch is indicating, I tried setting that port and every other port connected to the bridge to 10baseT-FD including the 2 ports on the bridge, that had no effect.

Noticed today that if I replace what was mentioned above as vlan2 (my dmz) with another switch I end up with no packetloss
In other words:
internet > vlan1 > bridge > anotherswitch

It really feels like I am stumbling in the dark.

Re: procurve 2424 vlan and bridge

what version of code are you running on the switch?

Do the losses appear to be related to a certain packet size? i.e. do small packets go through fine but packets above a certain size tend to have losses?

Re: procurve 2424 vlan and bridge

I'm running the latest version of software I could find.
C.09.22, ROM C.06.01

I played around with diffrent sized icmp-packets and it doesnt seem to make any difference.
all though I have seen some improvement down to *only* 20% packetloss but I haven't yet found the reason to that, seems to random.

Re: procurve 2424 vlan and bridge

dit you check if the 2224 got one unique mac@ table for all his vlans of one for each ?. If he has one unique table he can't decide if a computer is one one side or on the other side of the bridge. The same probleme occured with intel 460T switches. Try to use a 2824 if possible.
