tunnel routing question

Hi there,

A little question about tunnel configuration.

Firstly, here is a network config:

<pvt net>---[cisco3000]==L2Ltunnel==[cisco3000]---[fw w/NAT]-<internet>

Users in pvt network access internet through a lan-to-lan tunnel.

How do I specify that everything _except_ several networks should go through the tunnel?

I can't create a network list, since I can't list the whole internet.

Specifying 0.0.0.0/255.255.255.255 as network list for tunnel doesn't seem to work...

Thanks.

Hi there,

You still have to use Network list to achieve that. It will be a test on your subnet mask skills.

so for example, if you want to include all internet routes from 1.0.0.0/8 to 127.0.0.0/8, you can di it by :

1.0.0.0/127.255.255.255

Hope that helps
