Hi, When I first installed my bridge I got some behaviour like that. Then I changed the interfaces I was using on the bridge and tried again. Everything worked fine. It seems that one of the NICs I was using or its driver module, was slowing down the bridging process.
My suggestion would be, set up your bridge with other ethernet cards and try again. That worked for me. Regards, Edo ----- Mensaje original ----- De: "Juan C.

(the graphs shows min RTT and average RTT) (I'm sure this delays are intruduced by the bridge, if I stop the bridge everithing works fine) any ideas??? some data: bridge between 2 ethernet intefaces: OEM i82557/i82558 10/100 Ethernet brctrl addbr br0 brctrl stp br0 off # enable bridging in interfaces brctrl addif br0 eth0 brctrl addif br0 eth1 # setup interfaces ip link set eth0 up ip link set eth1 up # enable bridge ip link set br0 up thanks in advanced (excuse my horrible english) :P Juan Carlos Moreno. _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
