### set variables
# destinations you don't want routed through Tor

### get the UID that tor runs as
_tor_uid=$(docker exec $_tor_container id -u tor)
### Tor's TransPort
_trans_port="9040"
_dns_port="5353"
### flush iptables
iptables -F

### redirect all DNS output to tor's DNSPort
iptables -t nat -A OUTPUT -p udp --dport 53 -j REDIRECT --to-ports $_dns_port
### set iptables *filter
