I didn't actually try that.
I have actually been on to the ISP and have been told that there is an
ACL blocking that sort of thing on the router, but they are adding an
ACL to allow packets from the IPs in question.
So hopefully everything will soon be solved.
I believe I may have figured out how to do it using routing tables.
But I won't test this until I find out if the change on the router fixes
it as this is the neater of the possible solutions.
Thanks for all the help of everybody.
