I was thinking you were using O2's ftp servers. The only thing I can think of off the top of my head is that when at work you're on the same NAT addresses and when accessing externally you have to go via port 25 as the address you want to go to is ftp://xxx therefore their system does not recognise the address unless it is concluded with :25 once routed to your office the port number may be ignored and just the ftp://xxx part is used. Providing their firewall doesn't block transit Hence the static IP. This is just conjecture on my part as I haven't tried it.

Like that's gonna happen. Port 25 is usually only used for smtp, like they say using it for ftp will invoke the same rules as set up in their firewall for smtp. I'd change my service provider.

How on earth do commercial enterprises with ftp servers host them so everyone can access them? Thats all id like to do, but mainly me anywhere! Not everyone has a static ip! Apparently they dont block port 25 on a static ip at O2 so would this make some sort of difference? I dont see how, but im not too clued up! They assure me this is the only blocked port on a dynamic address.

I failed. It is another string to my knowledge to see how you or Duncan managed.

If the external port is >0 then it is unlikely your router is the problem. This is presuming you are using UPnP.
Tell me to shut up if I'm on the wrong track please.
@Duncan, everything is worth a try, even switching something in and out can sometimes magically fix this type of issue.
