Helpz ESXI Issues 9.3

xInsertx

Guys, having problems with a new box im setting up which is running utm 9.3 inside of esxi 5.5. It seems that clients can talk to UTM but UTM cannot talk to clients. Any ideas? Pulling my hair out as this is almost an exact copy of my existing setup.

Because clients can talk to UTM web surfing etc is fine. But because UTM cannot reach clients itself NAT / WAF / Routing / SSLVPN ofcourse dont work.

UTM is configured PPPoE on "VM WAN Network" and 3x ethernet vlans tagged on "VM Trunk".

    Bob thanks for the reply. Glade to see the community favs are still here after Astaro.org

    I've been using utm since 7.xx so I'm 99% sure it's to do with esxi. I actually have the rulz printed out for my co-workers =)

    It seems to be the sophos vm cannot initiate a connection via the vSwitch. I can ping utm. I can ping the web. Utm can not ping me. Utm can ping another vm using the same vSwitch. This VM can also not ping me.

    It's really weird it's like the port group or vswitch is doing something.

    So after remaking the Virtual Machine / vSwitches / Port Groups etc it still wouldn't work. So I changed the IP address of the internal NIC for utm. This worked!!

    So after abit of head banging it occurred to me the ARP table might be causing issues with a new MAC address using existing IP. Flushing the table of all devices (via command or reboot) and switches and bang everything works....

    Always trust networking to throw a spanner in the works =)
