SOLVED:connection issues, Nat and other.

[jhvisto]

after many checks, i do not know what still wron. latest:

Code: Select all

info: GPGNET: received nat packet from 87.127.18.209:20214
info: NET: using deflate compression for sends to 87-127-18-209.static-adsl.aquiss.com:20214.
info: LOBBY: rejecting unexpected connection from 87-127-18-209.static-adsl.aquiss.com:20214
info: GPGNET: sending nat packet to 87.127.18.209:20214


and opposite site log

Code: Select all

info: GPGNET: sending nat packet to 88.195.9.208:16350
info: GPGNET: received nat packet from 88.195.9.208:16350
info: LOBBY: rejecting unexpected connection from dsl-pribrasgw1-ff09c300-208.dhcp.inet.fi:16350


and why it opes that port from me? i set 6112 and that wasn't first time, it's like random port allmost everytime.
and also sniffing packet data:

Code: Select all

"192.168.1.33","217.140.180.11","UDP","Source port: dtspcd  Destination port: dtspcd"
user Datagram Protocol, Src Port: dtspcd (6112), Dst Port: dtspcd (6112)
Header checksum: 0x0000 [incorrect, should be 0xe71b]
(Error/Checksum): Bad checksum

so udp packets, and bad checksums. what now?

How's your OUTGOING firewall (often also in a router) configured?

[jhvisto]

in Zyxel 660hw-d1 there is only firewall On of Off.

and in windows, all outgoing is allowed to any port with udp or tcp.

[Ze_PilOt]

FA is (mostly) smart.

You told it to open on port 6112. It tries, but fails. So it open another random port.

That's why the first UDP packet you send is to the server (91.229.20.50:30351). The server receive it, and by reading the "header", know that your port is not 6112 but another port.

The fact that the other player send it to the correct new port proves that the system works.

What does not work is that FAF think it's an unexpected connection. The weird thing is that it's the case for both of us. Something is clearly wrong here, because it was not the case before. Did you change anything to your config ?

[jhvisto]

you mean game, faf lobby? or other? game was installed again 3rd time and its as vanilla at should be, so it is lobby, 3rd install as latest, other??? nothing that i do not know, i'v done nothin new, just tried to get this to work.

[Ze_PilOt]

I mean in your router/firewall.

[jhvisto]

router: there is no firewall on, nat is redirected to to right ip:
windows firewalls: udp or tcp. no allowing or dropping.

[Ze_PilOt]

I don't think it is, or FA would be able to get the port 6112. Maybe try another one.

[jhvisto]

tryied port 26112 and still nothing. both udp and tcp were open out. and in.

edit: after sinffing other udp traffic, those were ok, so is my lobby somehow corrupted or something like that?

[jhvisto]

and yet again: (reinstalled lobby and tried again with service ipsec disabled.)
