NAT type failed on Playstation

[sadoneli]

I compiled the newest shadowsocks-libev 2.2.3
Also upgrade the shadowsocks server to Shadowsocks 2.6.11 (pythoon)

however, when I play PS3 with udp relay mode through Tproxy (ss-redir)
It showed NAT failed.
I tried on my three VPS, all same result.

when I reconfigured the shadowsocks-libev 2.2.2
I get NAT3, which is expected.

Is there any chance to improve?

Verified on PS4.

@clowwindy Are we sure that the latest UDP relay change does not introduce side effects?

[madeye]

@sadoneli Could you also test dota2 or any other online game to see if the new UDP relay works with them?

[sadoneli]

@madeye I will test dota2,see if it works

[sadoneli]

@madeye
Getting into dota2 client is ok,
but when popup game accept, it fails.

I also test QUIC with google chrome, it works fine, the youtube video are streamed througt UDP.

when I reconfigured the shadowsocks-libev 2.2.2
I get NAT3, which is expected.

Does that mean shadowsocks-libev 2.2.2 client with shadowsocks 2.6.11 server works fine?

[sadoneli]

@clowwindy in my test, yes.

[clowwindy]

@sadoneli Can you also try shadowsocks-libev 2.2.3 with shadowsocks 2.6.10?

[sadoneli]

OK, I will test it
any convenient way to downgrade shadowsocks python server?
I installed ssserver through pip

[clowwindy]

pip install shadowsocks==2.6.10

[sadoneli]

I retest the dota2，it seem works fine
shadowsocks-libev 2.2.3 with shadowsocks 2.6.11 OK
shadowsocks-libev 2.2.3 with shadowsocks 2.6.10 OK
shadowsocks-libev 2.2.2 with shadowsocks 2.6.11 OK

I monitor the udp traffic on vps, and I can see dota2 game port (27000 - 27100) have traffic as expected

The test in this morning is wrong.

But when comes to playstation, still NAT 3(wrong ,it is still nat failed as the issue title mentioned)

[madeye]

For NAT3, which configuration are you using?

[sadoneli]

@madeye wrong typing ,it is still nat failed as the issue title mentioned,when usinig shadowsocks-libev 2.2.3

[madeye]

After some tests, I think it'd be a ss-redir specific issue, not related to new UDP multi-source change. I'm working on some fixes to this issue.

[madeye]

With NAT Type Test, now the NAT type becomes FullCone (NAT3), which is expected.

[madeye]

Tested in Garden Warfare, everything works well now. Other EA games should work now.

[sadoneli]

@madeye nice work!

[madeye]

Now NAT2 achieved!

[clowwindy]
