Is there someone ,who had a common problem. Two separate interfaces sounds a bit unusual to me (although it's a long time since I used ISDN). Shouldn't the choice be between one interface running at 64k or one interface running at 128k? I think this is an option in the isdnctrl setup, telling it to bond the two underlying channels together before binding them to an ippp interface? It surely isn't a netfilter problem - you can easily do masquerading on both interfaces with netfilter, but you will only be using one of the them as your default route. Try the man page for isdnctrl I think. Antony. -- Your work is both good and original.
