"Default Drop" of HTTPS packets on internal connection

mhibler
Hi guys,

Here's another one from my workshop [;)]

I have an ASG v8 as a virtual appliance (192.168.98.254) on a ESXi host (192.168.98.1).

I can not connect to the ESXi host with VMware vSphere Client from another internal PC (192.168.98.11).

Here's a Packet Filter log:

However, on a very rare occasion I do manage to connect just to be disconnected a couple of minutes later.

I have another ESXi host on the same network (192.168.98.2) which is working just fine...

What should I check?

Thanks in advance,

Miro

    A few days ago I activated the transparent HTTP and HTTPS proxy, then disabled it and could not use any connection on port 80 or 443 any more as those got ignored by any NAT rule. As a result all packets to port 80 or 443 got routed through the default gateway which was the wrong destination for example for some servers in a DMZ.
