Question: is it possible to set some capture filter to capture only these packets with 123 inside ? For this moment I have to capture all TCP packets into file and after that using display filter search for string 123 in the file, but it is not a good idea for me, because traffic is realy big, 

You might want to look at ngrep: http://ngrep.sourceforge.net/
