I have also encountered this problem. Have you solved it yet

You can setup redirections with tools like socat (#87) or use iptables-persistent rules to redirect ports.

Here is an example of rules (/etc/iptables/rules.v4) to redirect default FirmAE ports (replace enp0s8 with your default interface) :

*nat
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-A PREROUTING -i enp0s8 -p tcp --dport 80 -j DNAT --to 192.168.1.1:80
-A PREROUTING -i enp0s8 -p tcp --dport 1337 -j DNAT --to 192.168.1.1:1337
-A POSTROUTING -o tap1_0 -j MASQUERADE
-A POSTROUTING -s 192.168.1.1 -o enp0s8 -j MASQUERADE
COMMIT

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A FORWARD -i enp0s8 -o tap1_0 -p tcp --dport 80 -d 192.168.1.1 -j ACCEPT
-A FORWARD -i tap1_0 -o enp0s8 -p tcp --sport 80 -s 192.168.1.1 -j ACCEPT
-A FORWARD -i enp0s8 -o tap1_0 -p tcp --dport 1337 -d 192.168.1.1 -j ACCEPT
-A FORWARD -i tap1_0 -o enp0s8 -p tcp --sport 1337 -s 192.168.1.1 -j ACCEPT
COMMIT

Don't forget to enable port forwarding :
To do it the persistent way, edit the /etc/sysctl.conf file and uncomment net.ipv4.ip_forward=1.

Reload the service :
sudo service iptables-persistent reload

IPv6 may also be a problem for services that don't handle it, make sure to disable it if it's the case.
