Hi,
Any body know if we can achieve this:
A PC connected to a Cisco 877 router and 877 router is connected to another router (7301) via GRE tunnel,
Cisco 7301 router is a NAS server and is being used as a PPPOE server.
If user create a PPPOE connection on his computer and dial with a username/pass we want to send the PPPOE traffic to 7301 router, so 877 router should pass the PPPOE traffic to 7301 and user will be able to connect,
User -> 877 -> 7301(PPPOE server)
Thanks

Can this be achieved by configuring 877 router as a LAC server?

Hello Rassoul,
yes the right tool to extend PPP sessions including PPPoE ones is to use L2TPv2 that does this job nicely and it is used by service providers
Hope to help

Hi Giuseppe,
Thanks for the reply,
Could you let me know if the below config looks ok to you to configure 877 router?
877 router dialer0 interface has got a public ip address,

accept-dialin
protocol pppoe
virtual-template 1
vpdn-group 2

protocol l2tp
initiate-to ip X.X.X.X # ip address of 7301 LNS router
lcp renegotiation on-mismatch
l2tp tunnel password 0 XXXXX
l2tp tunnel nosession-timeout 86400
int vlan 1

Hello Rassoul,
usually a LAC/LNS pair uses stable IP addresses, that is the LAC is not also a client in another PPPoX session and this looks like the problem here.
Hope to help
