I have run some experiments with two DSL lines on single Cisco Router. The more things you want to do, the harder it gets to configure IOS the way you want.
1. It isn't hard to actually configure the two serial interfaces, correct?
2. You should be able to make the VOIP traffic go to ISP A by using policy based routing. In general, policy routing is your friend with multiple interfaces.
3. When you say NAT isn't working what do you mean?
It's not hard to make NAT work for a single interface right?
What you can easily do as a second step is assign different local IP ranges for different interfaces. For example 192.168.0.0/24 for ISP A and 192.168.1.0/24 for ISP B.
Getting NAT load sharing isn't too hard you can use "ip nat pool" with two "address" statements and then do "ip nat inside source list 10 pool test overload".
Post your current config if you have more questions. -- ~leb |
