UTM 2 external IP addresses

ciscoman

hi,

trying to setup UTM to use 2 external IP addresses (ideally round robin)

Physically it is only one interface, web requests to outside should appear as source IP1 and IP2.

Any ideas how to archive this? Uplink balancing refers to 2 interfaces ..

Secondary IP is possible, but as soon the UTM creates a tcp session(proxy/web filter), only primary IP will be used.

Rg

    I don't think you can achieve this on one link. I have 1 link serving 14 IP addresses to the WAN side. I use NAT settings to re-direct traffic. If you could provide some more details about what you are trying to accomplish it might help. What is the purpose of the 2 IP addresses.

    Hi.

    purpose is to be visible with different IP addresses on the remote side.

     

    many clients -> using UTM Web filter/Proxy -> public webserver

    Public webserver see as 'source IP always IP address UTM public IP x.x.x.1

    Goal is that the public web server might see several source IP addresses x.x.x.2 and x.x.x.3

     

    Regards

    Sorry, you're asking a Cisco question  - tell us what you want to do and you might find someone that doesn't think Cisco to help you. What do you want to get to where?

    Cheers - Bob

    Since you're talking about web filtering (proxy), it's really not the individual host that's communicating to the outside world, but your proxy is. I don't think it's possible to have the webfilter use different public IP's for different clients on just 1 physical interface.

    Using mulitpath rules it could be possible, but I think this only works with multiple WAN connections.

    not a cisco question. Nothing related to cisco
