I have configured VPDN/Dialer on router 2600 to connect to our ISP via Fibre Optics modem but its simply not connecting. I need someone to help out please. I'm new to this, so need a clear guide.
The router consists of 3 interfaces
- Inter fa0/0 = 10.0.0.6 255.255.255.248 (LAN 1)
- Inter fa0/1 = IP is unassigned (interface connected to Fibre Optics modem)
- Inter e1/0 = 192.168.200.1 255.255.255.0 (LAN 2)
The connection is planned to run like this:
LAN1 & LAN2 (Inter fa0/0 & Inter e1/0) <-> Inter fa0/1 <-> Dialer1 <-> Modem <-> ISP <-> Internet.
The Modem will just server as mere "modem" or just a bridge, as the actual routing is configured on "dialer interface" in the router.
We're not using a dedicated IP address to link to ISP but a public one.
After configuring the interfaces, VPDN, dialer interface, NAT, access-list, ISP's assigned username/password, etc I'm simply not connecting to our ISP, even when I do a ping. The ISP's IP address which we're pinging is 118.23.8.80
What am I missign out? How do I connect the dots here?

Okay. I see the traffic sourced from 10.1.12.1 . Did you try to source it from 192.168.xx.xx ?? Because I see, there is no NAT applied on that FE interface.
And on ISP facing FE interface, may be a pppoe-client dial-pool-number 1 may help.
04-19-2011 08:33 AM
Hi,
Thanks for the response, but the 10.1.12.1 is a subinterface configured in the router. I'm not pinging from a client under this interface but rather pinging directly from the router's console to the ISP.
Because I see, there is no NAT applied on that FE interface.
I've added the NAT on the interface fa0/0 as you suggested,
and.........
And on ISP facing FE interface, may be a pppoe-client dial-pool-number 1 may help.
I added this as well but its not connecting either.
When I ping the ISP, below are the error message it returns every 10 seconds or there about:
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 118.23.8.80, timeout is 2 seconds:
