Jails lost connectivity

[tranqme]

Hello,

I stupidly decided to rename the vSwitch in ESXi that my VMs were using and this has messed up the networking for my FreeNAS host/jails. I managed to sort out the host, although I'm still struggling with the jails.

At this point, the I can ping the jails from the host and vice versa. However, they are not contactable from any other device on my network, nor can they contact the outside world.

I also noticed some log messages appearing occasionally on the host, which concerns me as I recall seeing 'epair0/epair1' being used instead prior to the vSwitch change:

epair2a: Ethernet address: mac
epair2b: Ethernet address: mac

I've spent way too much time researching and trying different fixes to get these jails back up and running, and I would really appreciate some assistance as I don't wish to re-create them from scratch.

Host ifconfig:

Were you able to resolve this?

No, I was not. So far I have re-created one of the two jails though.
