Linux – multiple openVPN instances – tun1 fails

Various resources are on the below LAN, one of which is Linux openVPN server. For complicated reasons, I have to run 2 openVPN server instances, VPN1 and VPN2. VPN1 works great, hands out 10.8.0.x tun0 IP's to connecting clients. Clients are then able to access any resources on 192.168.44.x LAN, all is well.

VPN2 is setup using ifconfig, not server directive. This is because i have to manually enter tap-win32 tcp/ip static IP on VPN2's client (for reasons not explained).

After I start VPN2, I see 'TUN/TAP device tun1 opened' in log, but sudo ifconfig does not display tun1, only tun0…why?

Client is able to connect to VPN2 successfully, but not able to access any resources on 192.168.44.x LAN? I setup static route on LAN router for VPN2, (just as I did for VPN1) between 10.9.1.x and 192.168.44.x so this isn't the prob.

I have ip_forwarding enabled on openVPN server, i have 1194-1195 ufw firewall open on openVPN server.

any help would be great!

OK. above problem fixed by removing ifconfig-noexec.
Next problem…mapping to printer on 10.9.1.x VPNclient from 192.168.44.x LAN. The VPNclient is connected using openVPN-GUI. Sometimes \10.9.1.x\printer works, othertimes not, anyone deal with this before?

thanks!
