Firefox as local app and networking [SOLVED]

[M Rathburn]

The solution was to set on the LTSP server the option domain-name-servers in
/etc/ltsp/dhcpd.conf to that of my internet router.  Then, a static route
was needed in the internet router for 192.168.0.0 -> 192.168.1.25 for the
traffic to get back.  So yes, it was a combination of the suggestions
presented.  Thanks guys!  Here's the updated dhcpd.conf file:

#
# Default LTSP dhcpd.conf config file.

authoritative;

subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.20 192.168.0.250;
    option domain-name "example.com";
    option domain-name-servers 192.168.1.1;
    option broadcast-address 192.168.0.255;
    option routers 192.168.0.254;
#    next-server 192.168.0.1;
#    get-lease-hostnames true;
    option subnet-mask 255.255.255.0;
    option root-path "/opt/ltsp/i386";
    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";
    }
}
