Hi All,

So lets start from configuration:

ESXi 5.1 config.
Network Adapters x 2 Intel
NIC Teaming : Route Based on Originated Virtual port ID
Failover detection: Beacon Probing
Promiscuous Mode: Accepted on vSwitch
4 NIC-s for EFW, VLANs 1,2,3,4 for each NIC


EFW:
Promiscuous Mode: Accepted an all network cards.

GREEN  192.168.0.0/24
ORANGE 192.168.1.0/24
BLUE 192.168.2.0/24
RED: DHCP

VPN Config:

OpenVPN server enabled: Yes
Bridged: No
VPN subnet: 192.168.5.0/24
Protocol UDP
Port 1194
Block DHCP responses coming from tunnel: No
Don't block traffic between clients: Yes
Allow multiple connections from one account: Yes
Push This Nameservers: 192.168.1.10 (Domain Controller) (This bug was fixed in 2.5.2, in 2.5.1 this options didn't work. even via Account settings) 
Push Domain: localhomain.local
Authentication type: PSK (username/password)
Accounts: Username/password
Push route to blue zone: Yes
Push route to orange zone:Yes
VPN Firewall: Enabled, All VPN Users to Gree,Blue,Orange,IPSEC,VPNserver Service ANY ALLOW with IPS.


So what i get:

VPN not working.
1. My Android device is able to try connection with 'OpenVPN Connect', settings are pushed but i'm getting error :
"TUN_SETUP_FAILED info="tun_builder_error: ifconfig adresses are not in the same /30 subnet (topology net30)"

I tried to fix this by adding ' push "topology subnet" ' argument in /etc/openvpn/openvpn.conf.tmpl and after this i was able to establish VPN connection.

Exactly same is happening with Win7 x64 and OpenVPN client.

but cant access anything in my network, even cant ping 192.168.5.1, or openvpn server IP.

What is wrong? Please Help

PS. When I switch VPN Server to Bridged mode, Win7 is working perfectly, but Android device is not supporting TAP-MODE without rooting, etc. So I decided to stay on Nonbridge mode (TUN-MODE)

you need a app that supports tap - this one works wonderfully https://play.google.com/store/apps/details?id=it.colucciweb.openvpn&hl=en
