So I've added -steamport but now my command line was too long. Therefore I've removed +ip.
My command line consist out of the following:

-game 
+maxplayers 
+mapcyclefile 
+randommap 
+exec  
-insert_search_path  
-pidfile  
+sv_logsdir  
+mm_pluginsfile 
+sm_basepath 
-port 
-steamport 
+tv_port 
+replay_port 
+clientport 
-autoupdate 
-steam_dir 
-steamcmd_script
-secure 
-timeout 2
+rcon_password

I remember adding +ip because the server would not start but now it seems that everything is fine.

My questions:

1. Is +ip, -timeout needed, do you use it, can I savely remove it ?
2. Is there a way to "increase" or a workaround the 512 max limit ?

Last I checked -secure is unnecessary as it's the default.

Having said that, you may be able to move some of the + commands into the file you're +exec ing (although they'd be without the + in a cfg file).
