If i delete the multihome parameter there is no error anymore.
But i need this multihome right?

People can join my server via OPEN <IP> but not via UT3 Browser?
Whats wrong?

What are the chances that the game engine is thinking that all .255 IP addresses are broadcast IPs and are therefore not allowed to be used by a host? I've seen this before in some poor TCP/IP implementations but I would be surprised if this were the case.

Epic would have to answer that - its more of a rhetorical question that I posed.

Specific to your problem, are you hosting this server behind a home router running NAT? I assume if you are that your ISP gives your your IP address via DHCP based on the MAC address on your router. A way to test the problem that I described above would be to go into your router and tell it to "spoof" a new MAC address. In theory you should then get a new IP address (that isnt a .255 IP) and see if that one works.

And yes, I realize that Im likely barking up the wrong tree here - Id have to think that the engine is smart enough to know that a .255 IP can be totally valid under the proper circumstances. Im just throwing this out there as a remote possibility.

yes i am running this server behind a NAT but ports from 6500-7780 (UDP/TCP) are open.
Beside this others can join my server via OPEN IP but not via server browser. I will try that "spoof" MAC adress trick. brb

[gor9e]

indeed it was the ip ....

with another ip it works...

Thanks for following up. I reported a possible bug and pointed them to this thread.

I am experiencing the same problem. If I use the -multihome switch with my external IP, I get the "Failed to bind to port 7777..." error as well and it causes the server to crash. (My external IP is not a special one, like xxx.xxx.xxx.255.)

Is there a fix for this or were you just able to confirm that it is not yet supported?

Thanks in advance! -WB

Sorry it didnt work behind a NAT. Only after i removed my switchrouter (integrated NAT) it worked without problems.

I could not find any code that made specific assumptions about a broadcast address. I've asked QA here to reproduce the issue.
