Outbound and inbound FTP stopped working

"I have no idea what has caused pfSense to break"
You had a sniff of pfsense sending the traffic on - how is that pfsense broke??

Its sorta easy to change something you thought was small and break things…
Which takes me back to my statement 2 months ago. Wipe, reinstall. -

Which takes me back to my statement 2 months ago. Wipe, reinstall.Update from last night, the problem reappeared this morning with the new install.
reinstallagain with only no inbound rules at all and the default outbound NAT rules applied. Same thing is still happening. Not able to get the FTP data transfer happening.
In order to test i rejigged the windows host to bypass the firewall and connect directly to the internet FTP up and down works fine.
I have found a few posts on issues with Pfsense and Vmware Nics, has anyone ever experienced issue with PFsense on vamware ( esxi ) before?
In the original post on the subject I mentioned that the problem first arose after an unclean shutdown of the host. the only thing i can think of now is some weird interaction between Vmware and PfsenseKen

I am running pfsense on esxi, have been for years.
Dude you did a sniff on pfsense showing it sending the traffic on - and I thought you even had a sniff on the client seeing the traffic??? If not do that test again..
Seems to me is your ftp client/server is the problem and your looking in the wrong place..

yep we had packet captures that showed traffic both inside and out.
The ftp server my users are trying to connect to is accessible with no issue, from every other network / internet connection I have access to (6 different sites), and with as many different clients. Windows, Linux, smartphone. The ONLY site I cannot connect from successfully is those behind the PFsense ( and monowall) firewalls running i have tried on this Vmhost.
A windows server on the same vmnetwork but outside the firewall can ftp OK.The FTP server running behind this same vmhost, shows the same issues when trying to connect from outside regardless of what firewall I use. From within the VM network, I can connect to the ftp service running internally withing the protected network as long as do not have the firewall as the default gateway.
It seems that any connection to an FTP server that has the firewall in the path in any fashion fails.
As i mentioned all was working successfully with no changes to any of the clients, hosts, and networks up until the Vmserver was forced down.
The only thing I can now try is to replace the vmhost host itself ( or reinstall ESXi ) and see if the problem still persists.
The vmhost is the only place it can be failing.Ken
