Hi,

Have you tested if connecting a computer directly to the ADSL if it gets an IP via DHCP?

If it works, the router should be configured to obtain DHCP address and a default route.

Hi Federico,

DHCP is not enable on the router.

I use this router to provide Internet connectivy over the Internet and tunneling between 2 sites.

Head quarter----tunnel through Internet-----ISP---------Cisco837 router-------cisco 2620 router.

Any ideas?

Re: Unable establish ADSL connection with Cisco 837 router

Are you configuring the 837 ADSL connection directly or an Ethernet interface connected to an ADSL modem?

In other words, is the ADSL modem the router?
