This command should get the gateway IP.

Linux: cmd = "ip route list | awk '/^default/{print $3}'"

or perhaps

Linux: cmd = "netstat -rn | awk '/^0.0.0.0/{print $2}'"

OSX: cmd = "netstat -rn | awk '/^default/{print $2}'"

I don't have a freebsd system available to test this, but I think
this pattern should work:

re.compile(r'^(default|0\.0\.0\.0)\s+(\S+)')
