We use a Cisco 2621 and a NM-2CE1B (double ISDN PRI). 60 window-pc's can dial in, using one B-channel each.
for our application we need to forward broadcast packets from the ethernet interface to all the B-channels.
I tried this (part of the config)
' ! interface FastEthernet0/1 ip helper-address 192.168.100.255
! interface Dialer1 ip address 192.168.100.1 255.255.255.0 ip directed-broadcast '
This doesn't seem to work. Using a the 'ip helper-address' entry for each of the B-channels does but, is there any other way to forward the broadcasted packets?, as using many 'ip helper-address' entries, makes the router unusable slow...
TIA, Marcel.
