SSL VPN problems after upgrade to 9.100-16 (probable compression issue)

gilester
Hi

I am using UTM9. I have some SSL VPNs established from Mikrotik routers (the UTM9 is the server). This used to work perfectly.

Last night I upgraded to 9.100-16 and the SSL VPNs have stopped working.

The SSL live log is full of messages stating "Bad LZO decompression header byte: 69". Compression is OFF in UTM9 as the clients don't support it, this setting (and the settings on the client) are unchanged from pre-upgrade, when it all worked.

The clients connect fine, so the authentication is apparently working.

There is another error in the log, 
2013:05:18-11:14:46 steelblue openvpn[16411]: x.x.137.137:32830 WARNING: 'comp-lzo' is present in local config but missing in remote config, local='comp-lzo' 

Yet the checkbox for "use compression" in the GUI is firmly disabled.


Any help will be gratefully received!

Giles.

    The issue isn't compression, it's that the newer version is looking for the parameter set to "no" on the client side, too, but (I'm guessing) the client was set up when "no" was the default, and the parameter appeaered only when it had a value of "yes."  I think this is a "bug" in that an Up2Date should not require re-installation.

    Cheers - Bob
