[Openvpn-users] Strange problem connecting two subnets trough a vpn tunnel

[Vincent <tokar@xxxxxxxx>]

Hi,
  
   This represents what I am trying to do :

----------------------------        ---------------------------      
VPN     ---------------------------    ---------------------------
| 192.168.1.0/24 | -----  | 192.168.1.3     | ---------------- | 
192.168.0.253 |--- | 192.168.0.0/24 |
----------------------------        | 172.16.58.1     |    tunnel   | 
172.16.58.6     |    ----------------------------
    site A                     ---------------------------            
     ---------------------------              site B
                                      computer A                      
   computer B

The tunnel is working, I *can* ping any computer on either site from 
any computer on the other site. But (there is a but) I can't
establish any direct connection trough the vpn (for example :ssh,rsync).
But if I ssh computer B from computer A then I ssh a computer on site B, 
then I can directly ssh a computer on the site A.
So I am thinking of a firewall problem but I can't figure out what is it 
....
Here are the rules I apply on computer A and B:

iptables -A INPUT        -i tun0 -m state --state 
ESTABLISHED,RELATED,NEW -j ACCEPT
iptables -A FORWARD -i tun0 -o eth0 -m state --state 
ESTABLISHED,RELATED,NEW -j ACCEPT
iptables -A FORWARD -i eth0 -o tun0 -m state --state 
ESTABLISHED,RELATED,NEW -j ACCEPT
iptables -A FORWARD -i eth0 -o tun0 -j ACCEPT
iptables -A FORWARD -i tun0 -o eth0 -j ACCEPT

Thanks in advance

Vincent
