[Firehol-support] NAT assistance

[vendor33 at reticent.xyz]

Hello,

I am hoping someone could assist me with a configuration issue I cannot 
seem to get my head around.  I have Firehol setup on a VPS with IP 
address 2.2.2.2, one function of which is to provide OpenVPN services.  
For this configuration everything below works as expected.

However, I wish to additionally use the VPS and Firehol to translate 
incoming TCP traffic from a home server with public IP address 1.1.1.1 
to a remote server 3.3.3.3 port 9999.  Can someone please assist me with 
the necessary NAT configuration?  It does not require bi-directional 
traffic but does require traffic response to 1.1.1.1 since it is TCP.


Thanks
