| cisco 1751 & AT&T 6 Mbs DSL Service
Hello,
I am almost ready to give up on this but I thought I would give it one more try here, and hopefully find some help...
I have a Cisco 1751 pre-installed with IOS version C1700-K9O3SY7-M (This is the IP/ADLS/FW/IDS PLUS IPSEC 3DES )with WIC-1ADSL 1-port ADSL WAN Interface Card. I have AT&T DSL service (6Mbs down /768 up).
I looked and found different config types on the cisco and other network sites but none of them worked so far.
All that I am trying to accomplish is :
1)Use the 1751 as my DSL ROUTER / FIREWALL for DHCP and NAT to my local network (192.168.100.0/24),and port forward 3389, 22, 80 to 192.168.100.x...
I found and modified this config but the 1751 is still not picking up an IP from the DSL WAN side.
Here is the config i have so far.
! version 12.3
service timestamps debug datetime msec
service timestamps datetime msec
!
hostname DSL_ROUTER
!
ip subnet-zero
!
ip dhcp excluded-address 192.168.100.1

no ip http server
!
access-list 1 permit 192.168.100.0.255.255.255.0
dialer-list 1 protocol ip permit
!
end
Thanks in advance for your help. |

1 edit | Your access-list 1 is incorrect. It should be the following:
access-list 1 permit 192.168.100.0 0.0.0.255
Router access-lists use wildcard masks, not subnet masks.
Also, you'll want to either add DNS servers to your DHCP config or add "import-all" to the group to pull the ones your ISP assigns. |

Have you verified your PVC and encapsulation? I am not familiar with AT&T, but those are common misconfigurations. |

Alassane, if atm pvc 0/35 does not work, try 8/35. |

@everstream.com | Cool ! PVC 0/35 worked. I actually hooked for AT&T.
Thanks,
