Hello, hope someone can help.
Manage a corporate network.
5 subnets all sitting behind a firewall with ranges:
10.1.1.x - 10.5.1.x
default route out of the firewall is through the public IP address assigned to one of the port on the firewall onto the internet. All working fine, except now we have connected into a larger WAN that staff on our five subnets need to access from their own desktops.
The problem lies in that the sites (over 1500+) in the WAN also all begin
10.x.x.x, at the moment I have added in a few static routes at the firewall to direct the traffic destined for that domain out though the appropriate port in the firewall
ie route add -p 10.123.0.0 mask=255.255.0.0 220.127.116.11
But - I don't want to have to do this 253 times (also dont want to have to readdress our own domain) is there any clever way I can mask out our internal ranges and direct all traffic destined for the WAN through the correct port with one routing statement?
thanks in advance.
