Something i've never seen before

Really I'd just like to ask a question of the folks at BIS.

I was involved in a MP game the other day and had something I've never seen before happen.  During a mission 3 players lost connection to a server at the same exact time.  The strange part about it was that they were still receiving packets from the server (ie: they could still see what we were typing in chat) but the server wasn't receiving anything from them (we couldn't see what they were typing).  They did not lose their connections to the internet, could still browse web sites and were still connected to our teamspeak without any problems what-so-ever.

I am wondering if you could tell me, when a connection is made to a server with OFP, are both incoming and outgoing communication sent along the same path, or does the client resolve their path and the server respond along a different one?  (I'm not sure if this question makes sense, but I don't have a very good understanding of how the internet works, so ?)

Anyway, If you can think of any reason that this might have occured, please let me know, it would be very helpful.

Ops, almost forgot.

We were using v1.96 dedi. server when this happened, if that helps.
