Hello Everyone,
I can't seem to find what is the problem with my config. I get my client to connect to the LAC, the virtual iface connection is established and is visible from the sh users command. However, the connection doesn't even reach the LNS.
Can you please browse my config and let me know what is the problem?
Thank you in advance!

Hi Guys,
I'm happy to inform you that we've found the solution.
There needs to be an IP pair between LAC and LNS (on this topology at least).
The LAC DOESN'T need to contain the usernames, only the LNS needs to.
You need to add the domain to the CHAP user name within the LNS username config
of you use domain-search on the LAC.
After correcting these my dialer finally got the IP address from the LNS pool and thus the connection
is working.
Dialer1 77.0.0.1 YES IPCP up up
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
80.0.0.0/32 is subnetted, 1 subnets
C 80.156.137.244 is directly connected, Dialer1
77.0.0.0/32 is subnetted, 1 subnets
C 77.0.0.1 is directly connected, Dialer1
S* 0.0.0.0/0 is directly connected, Dialer1
