It means the port need to be within that range, for example using port offset 33000 is good because it's inside the range of 32768 to 61000.

Apparently Sony Xperia have a more stricter port usage based on this guy issue https://github.com/hrydgard/ppsspp/issues/14051

But it's near impossible to play with someone above ping 250-300 while its possible on GTA.

It's expected to have lags/delays on such high latency, depends on how the developer implements the net code.
And most adhoc games will try to sync their data on every frame, which means it need to be able to sync the data within 16ms on 60 FPS games or 33ms on 30 FPS games. (ie. 1 second = 1000ms divided by 60 FPS => need to render the frame within 16.667ms per frame)

So if the network latency is more than 16ms it will render the frame at slower rate, thus can cause FPS drops, sometimes the game need to freeze the screen waiting for data to be synced before rendering the frame (usually happened on fighting games).
So far Warriors Orochi 2 probably have the worst net code from my perspective, because it won't render any frame if there are incoming data in socket buffer (ie. it will keeps reading the buffer until there isn't enough data to be read before rendering the frame), so if a player is sending faster than the other player, there will always be incoming data in socket buffer thus causing the FPS to drops to 0~4 FPS (ie. looks like a slide show), reducing the socket buffer size helped preventing it from dropping the FPS too low, but VPN doesn't seems to like small buffer size Sad

There are also games that try to sync the data asynchronously in background without affecting the frame rendering, in this case the game will looks like having delays (ie. delayed action and jumpy movements like in Naruto Kizune Drive) which is similar to how MMO games worked on PC (ie. prefer delays than to freeze all movements while syncing)
