Hello everybody, i have few of firewall filter, so can anybody tell me how can i export these filters to another Router..
Funny you should use the word export.. 
/ip firewall filter export file=filter
That will save your filter rules to a file called filter.rsc. You can then transfer that file to your other router(s) either via winbox, ftp or sftp.
once you have the file transfered to your second router you can then import with this.
/import filter.rsc
