Configure firewall

1. Allow panel port(see app_port in /wgdashboard/src/wg-dashboard.ini)
ufw allow 10085/tcp
2. Allow awg server port (see ListenPort in /etc/amnezia/amneziawg/wg0.conf)
ufw allow 52853/udp
3. Enable routing
   edit  /etc/ufw/sysctl.conf
   uncomment three lines:

   net/ipv4/ip_forward=1
   net/ipv6/conf/default/forwarding=1
   net/ipv6/conf/all/forwarding=1

4. Set default policy for forwarding
   edit /etc/default/ufw
   set -   DEFAULT_FORWARD_POLICY="ACCEPT"

5. Add NAT rules for awg clients
   edit /etc/ufw/before.rules
   add all lines to the start of document:
   
   # NAT table rules
   *nat
    :POSTROUTING ACCEPT [0:0]

   # Forward traffic through eth0 - Change to match you out-interface
   -A POSTROUTING -s 10.90.90.0/24 -o eth0 -j MASQUERADE

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