I'm a newbie. I don't know what I don't know.

I have a machine running Tails with internet via WiFi, and I want to extend internet (tor) from that machine to other(s) via the ethernet interface.

I have connected another machine to the one with Tails, running Linux (Mint). I set up both ethernet interfaces with static ip's.

My understanding is that, to make this work, I just have to configure the firewall.

My attempts started by using ufw, following this post.

/etc/default/ufw

DEFAULT_FORWARD_POLICY="ACCEPT"

/etc/ufw/sysctl.conf

net.ipv4.ip_forward=1

/etc/ufw/before.rules

# NAT table rules
*nat
:POSTROUTING ACCEPT [0:0]

# Forward traffic through eth0 - Change to match you out-interface
-A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE

# don't delete the 'COMMIT' line or these nat table rules won't
# be processed
COMMIT

So far I didn't forward the traffic from wlan0 to eth0. I found these rules to accomplish that:

-A FORWARD --in-interface wlan0 -j ACCEPT
-A POSTROUTING --out-interface eth0 -j MASQUERADE

But i didn't get it to work. I don't know if it's something missing, or more configuration is needed, or the order of the rules, or if I have to use ufw syntax, or a mix of all those. I tried every combination I could Imagine.

I also tried the above rules usin iptables, with no result.

I should add that incoming internet is filtered.

Thanks for your attention and patience.
