<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">I have a road warrior configuration, where the road warrior is behind NAT, connecting from a Virtual Machine, through to the gateway 10.1.0.2.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">In the logs the source IP of traffic to the gateway is the default gateway on the public network that hosts the SS GW. 10.1.0.1.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">However – I have been firewalling (FORWARD chain) based on Virtual IP pools – e.g. To only allow Virtual IP Pool 10.4.100.X -> eth2, 10.5.100.X -> eth3. This
works fine when using a client that’s not behind NAT.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">The NAT’ing here is obviously breaking the firewall rules…<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">What do I need to do on my gateway to be able to get back to being able to firewall based on Client Virtual IP?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"HP Simplified Light","sans-serif"">I have looked into [1] the nat_up_down script, but don’t really understand the mechanics of this and if it is what I need? For example what is PH_IP_ALICE?<o:p></o:p></span></p>
