Thought I would post up my latest little tip, just spent the last hour trying to get my laptop to connect to my work PC, only to find as usual a single checkbox ruining my life.
Normally when working from I just jump on my normal desktop rig and off I run no issues. When I’m out and about I fire up my trusty Dell Adamo. This afternoon though I decide to work from the lounge as I was only loading data and doesn’t need alot of attention just the occasionaly an F5, silly idea on my part.
Although my laptop will quite happily connect using my 3G dongle, apparantly it didn’t feel the same way about using my wifi connect at home. Even though my desktop was connecting to work perfectly, the laptop VPN connection repeatly kept going to failover server and returning “Unable to reach server”
Ok troubleshoot time, can i browse — yes, ping VPN server — yes… hmmmm ok then, retry on desktop fine…. crap, test using 3G on laptop fine… ok it’s the laptop and wifi then… router firewall – check, router ports – check, reset router – no change wtf…… rebuild tcp stack – nope, recheck all settings – fine …. hang on I don’t share my internet connect untick… boom working.
That’s was all it was stupid ICS apparantly will stop Nortel VPN from connecting, I assume it must have something to do with IPtunnelling and security but apparantly doens’t deserve a custom “turn off ICS you fool” error.
Either way if you find yourself receiving “Unable to reach server” next time you try to VPN have a quick check to make sure ICS(internet connection sharing) is off.
1. Open Control panel -> click on Network & sharing center
2. Click on “Change adaptor settings”
3. Right CLick on the connection you are usng and select properties then click on the “Sharing” tab.
4. Untick “Allow other netowrk users to connect through this computer’s Internet connection”
5. Click Ok
and that’s it, reattempt to VPN and should be working. (maybe restart PC if fails)
Anywho time for some TF2, hope this helps
