Hi there all,
I've a Cisco 107 with an ADSL WIC, a PIX501 sitting behind it. My ISP has only given me a single public IP. The only place I want to do NAT is in my PIX. The PIX will do PPPoE quite happily.
Has anyone a config for running the 107 as a pure bridge, forwarding all traffic to another device, so I can get my public IP to the PIX's outside via PPPoE?
Much obliged,
Gary

yes you can do that... i had configure it in my office... but i am having ADSL router from some other company not of cisco... i am having ISP connection to ADSL router provided by the ISP... and that router connected with my CISCO 3000 series VPN concentrator... and by bridging i am able to configure the global ip address to my 3000 public interface...
i think this bridging follow the RFC 1483 ...
hope this will help you
rate this post if it helps
regards

I have this working but I quite frankly don't
understand it. Verizon ADSL in NYC.
! 837 config -- ADSL bridging
!
! In the working production config we have a private
! internal address on Ethernet 0
! and not "bridge-group 1"
! I have changed that for you.
!
! I HAVE NO IDEA IF THIS WILL WORK OR NOT:_)

bridge irb

Thanks to you both. Douglas, I often find myself doing things that work for no apparent reason!!! so I'll try out this config. ;)
all the best,
Gary
