Need Help On Wan Issue & VPN


Above is the Network of One of my customer. The issue is now they are using ADSL and they want to change it to DSL and create remote access Vpn on their network. So i install the new SHDSL card on cisco 2800 router and upgrarde the IOS to see the card. Now i can see theDSL controller card. But i am still confuse with configuration from my ISP given configuration. Here are their config.

In My Dsl card, I can only configure mode to ATM mode and ATM0/1/0 interface. But i do not have ATM0 interface. If i config DSL controller assume as  ATM0 it is okay?Moreover I cannot type command (DSL equipment type , DSL Linertate). If anyone know how to config on this one plz help me.

One more thing, i do want to do VPN on the window2k3 as Remote Access VPN with Preshared Key. If i do this one, which ports do i need to open on our ASA 5505. Please enlighten me. I am more on server side and not much exeperience on network. Thank you.


Re: Need Help On Wan Issue & VPN


The config provided by your SP is generic and you need to customize the same based on your hardware.

You need to make sure that you configure the right parameters as mentioned by your SP to avoid any issues while establishing the connectivity.

As you have mentioned you need to change the syntax to interface atm0/1/0 based on the wic card availability in your router.

All other parameters should be the same but you still can try out establishing the connectivity with the best max possible config noting down the config lines left our or unsupported by your device.
