Since it has become an issue with both the PS3 and the PC, you might want to look at what is going on with your network hardware. Try using the PC to ping a couple IP's known to be used by the client to see if they are reachable. If you know the IP the client normally uses, try that as well as these two:

199.91.189.31
124.150.157.158

If those ping OK, than you likely are getting out and back fine on standard ports--something may be hanging up when XIV is trying to use it's custom port assignments. Powering down your router (remove power cable) for a bit and then rebooting it might get it behaving again. Some routers just periodically have these little "brain farts" where certain features like DHCP and such just hang up and the "quick fix" is a hard reboot. Largely why you are frequently told to reboot all your network devices, from your modem forward to your PC as a first step... quick attempt at letting the devices recover from glitches on their own first. If you've made any changes to your router that may address NAT, Forwarding, firewall/security/etc., might want to undo them and test again.

If you were using static port forwarding before attempting to use the PS3, might want to try undoing that since you are running the client on two different machines now. Some routers can manage the traffic just fine without setting up specific forwarding rules. Could also try switching to UPnP port forwarding (note you will need to enable it on both the PC and PS3 game clients if you go that route).
