routing trought 2 routeurs

[staifan13]

Hello,
I have a problem routing a port trought Zeroshell .

mI have 2 routeurs . My first routeur (the gateway) is configured with a 192.168.1.0/24 adress on his lan .
my zeroshell is conected to my gateway on ETH00 with 192.168.1.7 static IP adress .
ETH01 is configures with 192.168.10.0/24 .
I have enabled the NAT o ETH00 and ETH01 .
I have a web server on ETH01 with IP 192.168.10.11 wich work on port 81 .

On my first routeur (the gateway) I configured the port forwarding from the WAN port 80 to 192.168.1.7 port 83 .

On zeroshell I configured the port forwarding from ETH00 port 83 to 192.168.10.11 on port 81 .

So this my routing table :

Chain PREROUTING (policy ACCEPT 1006 packets, 178K bytes)
pkts bytes target prot opt in out source destination
37037 4196K CapPort all — * * 0.0.0.0/0 0.0.0.0/0
1890 91064 Proxy tcp — * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80
0 0 DNAT tcp — ETH00 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:83 to:192.168.10.11:81
0 0 DNAT udp — ETH00 * 0.0.0.0/0 0.0.0.0/0 udp dpt:83 to:192.168.10.11:81

Chain POSTROUTING (policy ACCEPT 98 packets, 6687 bytes)
pkts bytes target prot opt in out source destination
146K 10M SNATVS all — * * 0.0.0.0/0 0.0.0.0/0
21288 1642K MASQUERADE all — * ETH00 0.0.0.0/0 0.0.0.0/0
95 12448 MASQUERADE all — * ETH01 0.0.0.0/0 0.0.0.0/0

Chain SNATVS (1 references)
pkts bytes target prot opt in out source destination

but it doesn’t work and I don’t understand why .

If any can help me …

Thank you .
