After upgrade single ESXi host to 5.5 , PPTP connections not working anymore

[ksattler]

Hi,

I have a single ESXi host upgraded to 5.5. On the host I'm running a router VM with a small Linux Debian 6 with shorewall. The last configuration change was in Dec. 2012.

In the time between the host and the VM were rebooted several times without any problems. PPTP connections worked fine.

After I upgraded the host to 5.5 the clients hang while starting a PPTP connection at the point "verifying username and password". I have already rebootet the host, the VM and the DSL modem, without success.

I also restored a old backup of the router VM... now I have installed a new VM with a minimal Setup, still no luck.

Can anyone confirm this?

edit: I have copied the VM to another standalone host running ESXi 5.1 Update 1. PPTP connections are working fine now. So the only difference is the ESXi version 5.1<->5.5. Any idea?

I had problems on my Debian box with VPN clients, changed all network adapters from E1000 to VMXNET3 and everything works like it did before update.

UPDATE. After changing to VMXNET3 VPN has very poor stability, in fact VPN connections that did not reset before, now reset several times daily.

Hello,

does applying this patch require VM shutdown and ESXi restart?

Thank you!

Best wishes,

It requires an ESXi host reboot. So in case you don't have vMotion, you will obviously have to shutdown your VMs as well.

I know it has been a while since you asked this question, but the answer is conditional if you have this configuration:

Your VM that you have the router setup on is using E1000 network cards. Try changing them to the VMXNET3.
