Thanks again for your reply, I did find it strange that port fowarding would be used for common ports, as my previous experience is that I have only had to use this for specialist software and games.
I am aware that pfBlocker rules are currently useless, what I am now looking to do is move the default LAN rule down the list one at a time to find the pfBlocker rule which is preventing email. Once I have found the culprit I can then delete it.
I am fairly familar with proxy, but must admit that it is not really needed in a home evironment, I can see the use in the commercial world where you may have many users all wanting the same web page!
I do take on board your comment about loading one application at a time, rather then loading several at once and then finding out there are problems. I guess that it is just impatience on my part.
As new user it is great to see a users community out there willing to help, I know you would not get this if you have just paid ££££ for a new Jupiter device, unless you have a service contract every call to a helpdesk would be chargeable.
