hi ! In my work, I have a iMac connected wirelessly to a hotspot, this hotspot has a restriction ports. I came with my ps3 and thought I could play on the PSN, so I linked my ps3 on the iMac, activated the internet sharing, set the local network. I can go on the internet on the ps3 but the PSN won't connect. The PSN use the port n° 5223. so my question is : can I route this port to be sent via the port 80 on the airport ? thanks !
