he said that i had a weird port (can't remember but i tink it was 61509, im not sure ).
O.o
That sounds strange; your computer does not only have one port. Maybe he meant the port where 5029 is redirected to by your router.
I do not know if it is possible to change the port SRB2 uses to host - if it is, it is most probably possible using a command line parameter. You could try to do that and set this port to 61509 or whatever. I do not think that this works, but you could try it. ;)
