Trouble Setting up VPN Client with Custom UDP Fragment Size and MSS

This is my first attempt at setting up my own VPN.  I followed all the steps on the OpenVPN wiki page and successfully pinged the server from the client.  I can't do much more than that, though, because I can't configure the MTU properly.  When I add the lines

fragment 1300

(as 1300 seems to be my maximum transmitted unit) and

mssfix

to client.conf, the server returns the line

Bad LZO decompression header byte: 0

over and over.  This happens even when I only have fragmenting turned on and not mssfix, but not the other way around.  I would just use

mtu-test

, but there doesn't seem to be an option for that in NetworkManager.  What am I doing wrong?
