Jordi, If your "old" ISP is blocking the outgoing packets with the "new" source addresses, then your best solution is probably to implement source-routing via the tools in the "iproute" package. The configuration can get pretty complex, depending on what you need to do, so you probably want to check out the Advanced Routing HOWTO: <http://www.linuxdoc.org/HOWTO/Adv-Routing-HOWTO.html> Hope this helps, Wayne -- Wayne A.
