Check out this post as well because there are some issues
in that configuration:

Could be an MTU problem:

If 192.168.2.0/24 is your internal subnet (as the leftsubnet in
your roadwarrior-net seems to imply) then it should be exactly
the reverse:

virtual_private=%v4:10.0.0.0/8,%v4:172.16.0.0/12,
                    %v4:192.168.0.0/16,%v4:!192.168.20.0/24
