Title: SME 8.0 VPN Issue
Post by: eiceic on November 21, 2013, 01:49:19 AM

I'm having an issue connecting to new 8.0 server -- everything looks setup like normal.   My client machine is working fine connecting to many other SME boxes.   

Here is the log file from the one that is not working...

Nov 20 18:51:32 gateway pptpd[5127]: CTRL: Client XX.XXX.XXX.XXX (I deleted this)  control connection started
Nov 20 18:51:32 gateway pptpd[5127]: CTRL: Starting call (launching pppd, opening GRE)

Nov 20 18:52:02 gateway pptpd[5127]: CTRL: Client (XXX.XXX.XXX.XXX) control connection finished


For comparisons sake, here is what it looks when I connect to another 8.0 server and it works:

Nov 20 17:41:12 linux1 pptpd[19275]: CTRL: Client (XX.XX.XX.XX) control connection started
Nov 20 17:41:12 linux1 pptpd[19275]: CTRL: Starting call (launching pppd, opening GRE)

Nov 20 17:41:12 linux1 pppd[19276]: Connect: ppp1 <--> /dev/pts/1
Nov 20 17:41:15 linux1 pppd[19276]: MPPE 128-bit stateless compression enabled
Nov 20 17:41:15 linux1 pppd[19276]: found interface eth0 for proxy arp
Nov 20 17:41:15 linux1 pppd[19276]: local  IP address 192.168.2.3
Nov 20 17:41:15 linux1 pppd[19276]: remote IP address 192.168.2.232


Any ideas?   

Thank you,

Chris,

You are certainly more qualified that most of us to troubleshot this issue. Anyway:

is your host in "server only" or in gateway mode?
If "server only", is GRE going through?
Any host side logging?

Thank you Alex.

The server is in server/gateway mode

The server is a VM in ESXi 5.5..   I just turned it off and built it the same way with SME 7.3 and the VPN answers fine.   So it seems to be a driver issue with the ESXi 5.5 and SME 8.   I have a number of ESXi 5.1 and SME 8 vpns working fine.

My experinece with ESXi 5.5 is that SME8 does not appear to work with the vmxnet3 nic..

very interesting -- thank you both!   I'll test SME 9 and ESXi 5.5 in my playground but keep it to SME 8 and ESXi 5.1 in production.
