[7.450][BUG][NOTABUG] SSL-VPN does not work as expected

Hi,

I've a problem connecting to my home-astaro with vpn-ssl. The VPN works, I get an ip-adress and I'm able to ping my pc at home. But...
- I can not connect with rdp to my server...
- I can connect with ultra-vnc to my pc...
- I can not use any network ressource on the network at work...
- I can not use anything on the web (behind our asg-320 at work)

The old behavior (7.402) was:
No problem with connections to home-server via rdp/vnc and servers at work via rdp/vnc at the same time. Websurfing via asg-320 at work without problems...

Regards,
Rainer

That's odd. Do you have auto packet filter rules enabled on both sides? Is there anything in the packet filter logs for the traffic that is not getting through?

I will test it tomorrow, as I'm at home now.
That what I've done:
Installed a new machine with 7.45, restored a backup from the old machine (7.402), download the new install-package from the user portal and installed this on my laptop.
Behavior as discribed above.
Installed only the new certificates on my work-pc with the "old" vpn-client. Same procedure...
I'll check the logs tomorrow...

OK. Sitting at home, connected with Sonic Wall VPN to my PC at work, wich connected back to my astaro at home. Ping ip on subnet at home from work - works. Trying to establish a rdp-session to a pc at home from pc at work - doesn't work.

Any idea?

That looks like it has connected without error. What do you have in 'Local networks' in SSL on the Astaro.

Strange. Once you establish the SSL VPN, can you access the WebAdmin on the internal IP on the Astaro? You would need to use something like https://IP.ad.re.ss:4444/.

OK, switched back to 7.402. Same Setup as before.
Connecting with Soniq Wall (Aventail) to my PC at work, connected back to my Astaro at home with VPN-SSL.

Trying to initiate a rdp-Session from my pc at work to my server at home - works (this doesn't work with 7.45).
Trying to use some network shares at work (from pc at work) while the astaro is still connected - works (this doesn't work with 7.45 either).

Strange...

Rainer.

Hello,

My gut feeling is this one is an interoperability issue.

As you know we have a new SSL VPN package.  The tunnel completes successfully so usually there are only 2 likely issues at play.  first, on the ASG do you see any dropped packets?  (check the packet filter, ips and im/p2p logs).  My gut (which is starting to look like a crystal ball[;)]) says you probably aren't.

Next, what do your client side routing table(s) look like?  Do you have any 3rd party AV/firewalling products that can mangle/drop packets or alter routes?  we have seen this before.  Also, did you install the client using the local administrator account on the PC?

and as a last thing to check, do all of these things fail using hostnames or IP addresses?

Hi Tom,

As I posted yesterday, I've switch back to version 7.402 for testing. Now I'm at work, so a swap to 7.45 isn't possible at the moment. I do this after work today.

Yesterday, I've done a route print with 7.45 and one with 7.402. Here are the results:

This is the routing table with 7.45:

@Bob
I can connect to my Astaro at home from work.

Question: I've just discovered a problem with our proxy-auto-config with wpad (dhcp-option 252). Could this cause the problem?

Greets,
Rainer.
