VPN Forwarding

Task

Share vpn for other hosts in LAN.

What we need to do

1. Share host

First, we need turn on ip forwarding option in sysctl:

echo "net.ipv4.ip_forward=1" > /etc/sysctl.d/local.conf

Add NAT to net interface:

iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE
where br0 - vpn interface

2. Client hosts

Here we need only add route to route table:

sudo ip route add [LAN_gateway]/[submask] via [shared_host_ip]

That’s all. Now you can enjoy it!
