Thanks for quick response...
so now i know i required bridge. i have configured the bridge file for the subnet. but when i run it after some time it shows "squiggle has encountered a problem and needs to close"
my conf file for 1st subnet:
<internalservicebinding ip="10.10.x.0" port="1235" />
#i have given network address. is it correct or i should give IP of that PC?
<externalservicebinding ip="10.10.x.0" port="1236" />
<channelbinding ip="10.10.x.0" mport="9998" sport="9997" />
<add ip="192.168.x.0" port="1234" /> #i have given network address of remote subnet. is it correct or i should give IP of that PC of remote network?
