Hi guys, new member here looking for some expert advice on my router settings. I have done a self install and have a good connection to ADSL but for some or other reason can't connect to my office VPN. I have asked for advice from our IT department but suspect that they are also clueless. I have disabled the Windows firewall and also the NAT settings in the modem and tried connecting to VPN but it states that the banner is not recognised. We use Nortel VPN Client by the way. Any suggestions on what I can try? Sorry but I am a novice techo so you'd need to be very descriptive and patient...:D
 
Your router is most definitely not able to connect to that VPN, or any other VPN over PPPoE for that matter.

I'd say that you should first try to get your ADSL up and running (with NAT enabled) so that you can surf the web, before trying to even connect to your office's VPN service.

Once you have your Internet working 100%, then you can ask your IT guys for the hostname (DNS record to be exact) of the VPN server and see if you can ping or nslookup it.
To use nslookup: open Command Prompt and type in 'nslookup <hostname>' and press ENTER to run it.
eg. nslookup vpn.mycompany.co.za

If the nslookup got a successful response, then it would probably look something like follow:
Code:
Server:  router.home
Address:  192.168.1.1

Non-authoritative answer:
Name:    vpn.mycompany.co.za
Address:  123.123.123.123
^^ The first paragraph is the information regarding the DNS server that nslookup used to lookup the IP address associated with the hostname/DNS.
The second (Non-authoritative answer) paragraph is the details about the hostname. So you want an IP address that is associated with the hostname, and not something like the following:
Code:
Server:  router.home
Address:  192.168.1.1

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to router.home timed-out

Edit:
Why do they use Nortel VPN and not something like OpenVPN, or something that most operating systems (incl Windows supports) like IP2Sec/PPTP?
