Demon's Souls: Issues when using two PCs on the same network.

[Lil-Sassy]

X/Post from the official rpcs3 repository.

Quick summary

Unable to connect two PCs that are on the same network together through games that use RPCN (Demon's Souls).

Details

Trying to play Demon's Souls with my roommate

We can connect to other people without any errors but if we try to connect to each other it will always fail but only through RPCS3/RPCN. Fog wall will go up as will the Summoning Phantom / Being Summoned message

If we use two PS3s and connect to Yuvi's server, it works just fine.

When using two real PS3s (on the same network) connected to Yuvi's server. We can play together perfectly fine.

Last I checked (perhaps about a month or two ago) this was still an issue. I assume it's a simple port conflict?

In my situation I had two friends playing on the same network, while I was on a separate. They were unable to summon one another successfully, however I was able to summon one of them, but not the other. They could both connect to the server, and see summon signs and whatnot, but any attempt at forming a "lobby" - or whatever you'd call it in Souls - would only work with whoever'd been assigned the port that was being used. We did manage to switch who was assigned the port, but naturally that only left the other person unable to join.

@RipleyTom Are there any plans to resolve this issue, if it is not resolved already? Would a fix be as easy as allowing clients to specify what port(s) they use for RPCN?

This was solved with RPCN 0.6.
