Problema 1841 duas adsl

ola estou com um cisco 1841 com duas placas adsl gostaria de ajuda para fazer as duas placas autenticar e navegar cada uma separadamente com faixas diferentes
tentei varios scripts mas até agora nenhum me ajudou
quando autentica a nat nao funciona
ou as vezes nem autentica

ja possuo um 877w funcionando perfeitamente
ja o 1841 ta complicado

manda a config dele ai.

basicamente teras que usar nat + pbr

com esse script funciona apenas uma adsl por vez quando as duas estao sincronizadas apenas uma

Configure o NAT usando PBR.



!NAT dinâmico para os dois links
ip nat inside source route-map RM-1 interface Dialer1 overload
ip nat inside source route-map RM-2 interface Dialer2 overload
!
!ACL para permitir a LAN1 ser nateada
ip access-list extended NATacl1
permit ip 192.168.0.0 0.0.0.255 any
!
!ACL para permitir a LAN2 ser nateada
ip access-list extended NATacl2
permit ip 172.16.1.0 0.0.0.255 any
!
!Route Maps para os NATs
route-map RM-1 permit 10
match ip address NATacl1
!
route-map RM-2 permit 10
match ip address NATacl2
!

vou testar desde ja agradeço
