Hello I would like to ask you how to configure a Cisco 2600XM (with 2 FE ports) with an ADSL Line (RFC1483) and an external eth modem.
I have a 2651XM, on FE0/0 I have an external ETH modem, on FE0/1 I have the LAN side 192.168.0.254/24
With an ADSL Wic I configured the cisco as the following:
interface FastEthernet0/0 description Interfaccia verso la backbone interna ip address 172.16.0.241 255.255.254.0 no ip redirects no ip proxy-arp ip nat inside ip virtual-reassembly standby delay minimum 20 reload 20 standby version 2 standby 10 ip 172.16.0.1 standby 10 preempt delay minimum 20 reload 20 sync 10 standby 10 name R1A+R3P standby 10 track 1 standby 10 track ATM0 hold-queue 100 out !
interface ATM0/0 description ADSL bandwidth 512 bandwidth receive 7000 no ip address no ip redirects no ip proxy-arp atm ilmi-keepalive dsl operating-mode auto ! interface ATM0/0.1 point-to-point ip address 89.186.xx.xx 255.255.255.252 ip access-group 100 in no ip redirects no ip proxy-arp ip nat outside ip virtual-reassembly pvc 8/35 encapsulation aal5snap ! !
How should I configure an external adsl modem?
