I need to configure my Cisco877 just in bridge mode between ATM interface and interface VLAN1 so my PC would get public ISP IP address. I think this is done just setting my windows xp network interface for DHCP client. Could anyone send me or post this configuration file?
Thanks a lot!!!

Hello Adis,
it should take an ip address by DHCP to give your PC a chance to telnet successfully.
You have ip routing disabled so the router can behave just as a PC.
Hope to help

Hello Adis,
use the following
this mode of operation is called RFC 1483 bridged mode
http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a816.shtml
adapt the configuration to your needs use the document as a template

I tried this last night, buy it did not work. I was waiting for my windows xp network interface card to get the ISP IP address but nothing happened.
May be I was too tired to see the solution.
I will try your configuration one more time this evening.
Thanks a lot again!

Hello Seba,
check what the ISP is giving you: if it is PPPoE you need a PPPoE client on your PC instead of DHCP
note: I've linked a document in the cisco web site

No, it is not PPPoE o PPPoA.
It is just Ethernet.
Is it OK???

Hello Seba,
>> No, it is not PPPoE o PPPoA.
then you need DHCP on the PC indeed
the configuration is fine because bridging doesn't care of upper layer protocols

It works!
I tried this configuration this afternoon and it worked. I also defined DHCP client on my PC network card.
You can have a look at it:

Hello Adis,
nice news it worked
be aware that in this way you have configured the router as a bridge and you can access it only via console.

Yes, I know that.
In that case, is it enough to add an IP address to VLAN1?
Thanks!
