Mikrotik and Squid(Ubuntu based)

Dear all,

I am using Mikrotik(5.20) + Squid Box(ubuntu based)… i am facing an issue that squid is blocking my Media server IP(this i have connected after mikrotik)…

Can any one pl tell…how to exclude a specific ip address(media server) in mikrotik DST-NAT RULE so that mikrotik should not send sharing server request to squid, it should open it directly ..???

in your nat rule you can set !scr-address=ip_mediaserver

so any ip except ip of mediaserver is redirected to squid box.
