Hi to all,
Probably for you is a studip problem, but for me...
I have a Router 2811 configured as firewall and CME, and as gateway to ADSL a router 837 series.
Until yesterday I have only one ADSL, but now we need an other ADSL to split client traffic and server traffic.
I configured an other 837 router to with the ADSL, each adsl had 8 ip subnet.
It is enougth to configure and other ip route with same weight?
Like this:
ip route 0.0.0.0 0.0.0.0 111.111.111.111
ip route 0.0.0.0 0.0.0.0 222.222.222.222
and reconfigure the NAT pool for client?
Thank you very much.
Augusto.

Configuring two equally weighted static routes will cause them to load balance.
If I'm understanding correctly, you want your clients to use one ADSL router and your servers to use the other.
Let's pretend your servers are in the 192.168.1.x range of IPs and your clients are in the 192.168.2.x range of IPs
Try this:
access-list 101 permit ip 192.168.1.0 0.0.0.255 any
access-list 102 permit ip 192.168.2.0 0.0.0.255 any
route-map TEST permit 10
match ip address 101
set ip next-hop 1.1.1.1
route-map TEST permit 20
match ip address 102
set ip next-hop 2.2.2.2
interface f0/0 (whatever your inside interface is)
ip policy route-map TEST
You then no longer need your static route.

Hi, you understand perfectly, it seems easy... but now I have also some static NAT/PAT (for servers that I don't want change) and dynamic NAT (for clients).
Then I cannot change IP ranges. Can I make a access-list with subnet like that:
access-list 107 permit ip 192.168.254.192 0.0.0.63 any (all server ip are higher then 192)
access-list 108 permit ip 192.168.254.0 0.0.0.63 any
access-list 108 permit ip 192.168.254.64 0.0.0.63 any
access-list 108 permit ip 192.168.254.128 0.0.0.63 any
route-map TEST permit 10
match ip address 107
set ip next-hop 1.1.1.1 (old adsl)
route-map TEST permit 20
match ip address 108
set ip next-hop 2.2.2.2 (new adsl)
Thank a lot
Augusto

Yes those ACLs should work just fine.
