Please help resolve routing issue.
Thanks in advance!!!
I am not getting that you your request is going to 192.168.1.6 every time for both network
In your senarip simply configure like this :
--- > We have two networks 192.168.1.0 and 192.168.15.0
configure the IP address of firewall on user PC ie :
192.168.1.1 for 192.168.1.0
192.168.15.X ( the ip that configure on firewall ) for 192.168.15.0
the add default route towards internet gateway i.e. ISP IP or the interface that connect to internet.
