Openvpn – Tomato to OpenVPN Server on Ubuntu Server

I use OpenVPN on Ubuntu Server as VPN Server, and Viscosity successfully working with this client configuration:

xxx.no-ip.org remote udp 1194
dev tun
tls-client
ca ca.crt
cert cert.crt
key key.key
tls-auth ta.key 1
persist-tun
persist-key
persist-local-ip
auth-user-pass
comp-lzo no
nobind
pull
dhcp-option DNS 192.168.8.1
BF-CBC cipher

Now, I want to implement that configuration in my Linksys E2500 flash with Tomato (v 1.28 shibby)
This configuration of what I have done;

'VPN Tunneling > OpenVPN Client' menu

'Basic' tab:

• Start with WAN: Check
• Interface Type: TUN
• Protocol: UDP
• Server IP address / Port: 1194 xxx.no-ip.org
• Firewall: Automatic
• Authorization / Password Authentication: Check
• Username: myusername
• Password: *******
• Username Authen. Only: Uncheck
• Extra HMAC authorization (tls-auth): Outgoing (1)
• Create NAT on tunnel: Uncheck

'Advanced' tab

• Poll interval: 0
• Redirect traffic: Uncheck
• Accept DNS configuration: Strict
• Encryption cipher: BF-CBC
• Compression: Disabled
• TSL Regeneration Time: -1
• Connection retry: 30
• Custom Configuration:
  persist-tun
  persist-key
  persist-local-ip
  comp-lzo no
  nobind
  pull
  dhcp-option DNS 192.168.8.1

'Keys' tab

• Static Key: [content of ta.key file]
• Certificate Authority: [content of ca.cert file]
• Client Certificate: [content of cert.crt file]
• Clent Key: [content of key.key file]

and I was able to do 'Start Now' but this seems not work because I can not access any resources on the network under the VPN server which that I can do when I connect with Viscosity.

So, what I miss?
