Re: FW: DNAT SSH

I think the following can work.

1. -s anywhere --dport 5000 -j DNAT --to-destination :22

-s subnet --dport 5000 -j DNAT --to-destination 22

This will do nating only only subnet.

Thanx.

FILTER INPUT chain:

2. -s subnet --dport 22 -j ACCEPT

3. all others -j REJECT

The problem is the packet arrives on 5000 and is natted to 22 correctly
(1. - all good so far),
but because its source IP is not the local subnet (defined in 2.), it is
rejected in the filter
INPUT chain (3).

So I'm think something like the following:

a. can the packet bypass the INPUT filter chain?
b. how can I identify my natted packet within the INPUT filter chain and
thus ACCEPT it?
