Thanks for your help.
I forgot to mention the steps I did to setup the bridge.
I have 2 ethernet cards, eth0->to internet,
eth1->192.168.* natted lan.
I'm using a Debian with hotplug and in
/etc/network/interfaces I have the following lines:
iface pan0 inet static
pre-up brctl addbr pan0
pre-up brctl addif pan0 eth1
pre-up ifconfig eth1 0.0.0.0
address 192.168.111.1
netmask 255.255.255.0
up brctl setfd pan0 0
up brctl stp pan0 disable
up /etc/init.d/dhcp3-server restart
post-down brctl delbr pan0
post-down ifconfig eth1 192.168.111.1 netmask 255.255.255.0
post-down /etc/init.d/dhcp3-server restart
iface bnep0 inet static
address 192.168.111.70
netmask 255.255.255.0
pre-up brctl addif pan0 $IFACE
up ifconfig $IFACE 0.0.0.0
down brctl delif pan0 $IFACE
iface bnep1 inet static
address 192.168.111.71
netmask 255.255.255.0
pre-up brctl addif pan0 $IFACE
up ifconfig $IFACE 0.0.0.0
down brctl delif pan0 $IFACE
When the first PDA is connected I get the following in the syslog:
net.agent[7222]: invoke ifup bnep0=hotplug
kernel: device bnep0 entered promiscuous mode
pand[7220]: New connection from 00:80:C8:1F:E3:77 bnep0
kernel: pan0: port 2(bnep0) entering learning state
kernel: pan0: topology change detected, propgating
kernel: pan0: port 2(bnep0) entering forwarding state
dhcpd: DHCPREQUEST for 192.168.111.171 from 00:80:c8:1f:e3:77 via pan0
dhcpd: DHCPACK on 192.168.111.171 to 00:80:c8:1f:e3:77 via pan0
When I connect the second one:
net.agent[7271]: invoke ifup bnep1=hotplug
pand[7269]: New connection from 00:40:05:60:5A:14 bnep1
kernel: device bnep1 entered promiscuous mode

dhcpd: DHCPDISCOVER from 00:40:05:60:5a:14 via pan0
dhcpd: DHCPOFFER on 192.168.111.172 to 00:40:05:60:5a:14 via pan0
dhcpd: DHCPREQUEST for 192.168.111.172 (192.168.111.1) from
00:40:05:60:5a:14 via pan0
dhcpd: DHCPACK on 192.168.111.172 to 00:40:05:60:5a:14 via pan0
When I disconnect the first one (bnep0) first:
net.agent[7299]: invoke ifdown bnep0
kernel: pan0: port 2(bnep0) entering disabled state
kernel: pan0: port 2(bnep0) entering disabled state
kernel: device bnep0 left promiscuous mode
# brctl showstp pan0
pan0
STP is disabled for this interface
When I disconnect also the second one (bnep1):
kernel: pan0: port 3(bnep1) entering disabled state
kernel: pan0: port 3(bnep1) entering disabled state
kernel: device bnep1 left promiscuous mode
net.agent[7319]: invoke ifdown bnep1

Diego
