You can actually do a lot of interesting policy routing and load balancing
with both dynamic and static routing if you use two 2501s with two dte/dce
cable. I would load the 2501 with 12.1(2)T codes or higher so it can pick
up the ip address via dhcp from cable modem provider. Uplink the
cablemodem to the 2501's ethernet0 port. From that 2501, connect the two
serials back to back with the other 2501. Then your second 2501 will have
another ethernet0 going to your internal LAN. You can then do nat'ing on
the first 2501. Below is your a little diagram to help you visualize
better:
R2(s0)-------R1(s0)
Hub-----R2(e0) R1(e0)----------cable-modem----->internet
R2(s1)-------R1(s1)
You just need to enable nat'ing on the R1 and assign a private block on
the R1, something like 192.168.1.0/24 should be sufficient.
