Single asa5510, two public IPs for WebVPN

simh

Level 1

We have an asa5510 running as an SSL VPN gateway using one public IP address (e.g. 1.1.1.1) as the target IP address for the users.

Now we need to run a 2nd public IP address on the same asa5510 as target IP address for a different set of users, e.g. 2.2.2.2.

NAT is not working, secondary IP address is not possible, sub-interface is not the right way.

Does anyone see a way? Is this really not possible?

Thanks for any comment.

Hey,

You can try this out:

  • Create a new interface, let's say 'Outside2' and configure it with the second public IP address.
  • Enable WebVPN on the 'Outside2' interface and configure it the same way existing outside interface is configured for SSL VPN.

For all the TCP to-the-box connections, you should be able  to establish a connection to both the interfaces irrespective of the  the default route.

This should work!

HTH!

Regards,

Nick
