VPN Not Working

[#1]

I've recently moved house and joind Plusnet and am attempting to work from home on my work laptop for the first time today and VPN is not working. Well it is in that it says it is connected and i can get on to the web but when I try to open my Outlook it says the server is unavailable. I've looked at my firewall as i saw that on some other posts and have been in contact with both my IT service desk and plusnet customer services. Both of whom say - nothing to do with me!!!!! My router is the technicolour one if that helps as i've read it may be something to do with that.
Any help would be massively appreciated! I'm not overly tech savvy so please speak slowly!!

I dont use the technicolour router myself. However when I first setup my router i to go into the router config and enable VPN Passthrough, there is usually 3 options PPTP, L2TP and IPSEC depending on the VPN technology your company use. Do you have the model number and ill see If I cant grab the menu options for you.

Oh and the VPN is Citrix Access.

I couldn't find any ALG (Application Layer Gateway Settings) for the Technicolour. It seems not to have them. However you should check that the PlusNet Broadband Firewall is either OFF or set to LOW to work with VPN: https://portal.plus.net/my.html?action=firewall
Other than that you may need ot contact your IT helpdesk and get the ports that CAG uses and manually forward them.

It does have ALG helpers for PPTP and IPSEC. There's information here http://npr.me.uk/vpnissue.html#vpnpptp on disabling them to see if that fixes the problem.
