Configure WIC-1ADSL

Hello people!

I'm Sao Paulo - Brazil and here my ISP Telefonica work with RFC 2864. I need configure my interface WIC-1ADSL with following IPs.

It is easy part.

Fixed IP = 189.19.35.xxx

Gateway = 189.19.35.yyy

Mask = 255.255.255.0

Here it's my question. How to configure its on WIC-1ADSL? It's possible or I need another interface which work with encapsulation?

WAN = 172.20.7.170

Gateway = 172.20.7.169

Mask = 255.255.255.252

On my modem SpeedTouch I have a same configuration.

Hello Antonio,

my guess is that your provider may be using RFC 1483 bridged where

IP/ethernet/AAL5 is carried over the ADSL line.

That it is different from an RFC 1483 routed where you have:

IP/AAL5 over ADSL line

refer to this document and look at the configuration part customer side = CPE

Hope to help

Giuseppe

Hello Giuseppe,

I'll try that.

Thank you very much.

Let me know if you need a sample bridging config -  I have multiple sites set up for it.

Hello!

If you can. I'll be very happy.

I'm fighting with this inteface.

Thank you very much.
