Port 8080

Right, this sounds really stupid but....

I set up a webserver in the office that listens on port 8080, configured the router in the office to forward 8080 to that server. The same server is also running SSH, VNC and webmin on port 10000

When I get home i try getting to the webserver on 8080 - i get server not found error. VNC connects fine, webmin connects fine on port 10000, SSH connects fine. Port 8080 - not found. Phoned a colleague, he gets onto 8080 fine from his home. Tried from a different PC on my network at home - 8080 not found. Tried getting to the server on the browser on my phone & its OK.
I cant get to any sites using 8080 eg http://glcfapp.umiacs.umd.edu:8080/esdi/ or http://servlet.sanger.ac.uk:8080/das/

So, the problem is either my router config - or Plusnet is blocking 8080. I don't see any config on my router that would block 8080 - it's a 3com office connect wireless modem / router.

So, any ideasHuh

Cheers,
David

I regularly access and work on a remote server running on port 8080.

Maybe your router or firewall is blocking it?

Plus net isn't, or I'd not be able to access a Tomcat server on port 8080. I can, and have been able to do so since the server went live.

I can also open the two URLs you gave.

PlusNet certainly don't block access to 8080. As this isn't a PlusNet specific issue I'm going to move this to the Computers and Hardware forum.

Yes, after a bit more fiddling with the router config I found that if i switch the firewall off on the 3com router then i can access sites on 8080. if i switch it on I can't. So it's not plusnet, it's my router. But I've removed all the routing rules from my router config and it will still only work when the firewall is off. obviously I'd like to leave the firewall on...

I didn't think PN would be blocking 8080 deliberately cos it's used a lot for a non-standard http server port...

the router is a 3com office connect 3CRWDR100A-72 if anyone has experience of that specific device

Right, I fixed it.

I set up a "Special Applications" port triggering rule on port 8080 and now I can access any sites on 8080. God knows why the router is blocking 8080 in the first place, but adding that rule seems to fix it, without switching off the firewall.

8080 perhaps had something to do with the external web admin port of the 3com = conflicts? Dunno.. just a guess.
