vpn only works in non-split mode

[sdetroch]

Hello all,

We are new with openvpn (currently using checkpoint) and are testing the openvpn access server.
We installed the ubuntu vm image and upgraded to the latest version.

When testing, the vpn connections seems to work without any problem when in 'internet' mode.
When in split mode, the vpn is connected as well, but connections to the intranet are not working anymore.
I *think* that this is a beginners config error, but can't find what went wrong.

Server is behind checkpoint firewall and ports UDP1194, TCP443 are open towards openvpn server.
Only external ip's are being used (and I think here is the problem) --> the openvpn server is in the same subnet as the subnet I want to reach
Example: 195.0.0.0/24 is the subnet and server has ip 195.0.0.10/24
195.0.1.0/24 can be reached without any problem (and as previously explained, 195.0.0.0/24 can be reached as well, but only in internet mode)

What should I do to get access to 195.0.0.0/24 in split mode?
Preferable something at the server side, since I do not control all clients that will connect later on ...?

thanks!
