+## 7. Transparent Proxy with dnsmasq
+
+#### Setup a redirect proxy and a dnstunnel with glider
+glider.conf
+```bash
+verbose=True
+listen=redir://:1081
+listen=dnstun://5353=8.8.8.8:53
+forward=http://forwarder1:8080,socks5://forwarder2:1080
+forward=http://1.1.1.1:8080
+strategy=rr
+checkwebsite=www.apple.com
+checkduration=30
+```
+
+#### Create a ipset manually
+```bash
+ipset create myset hash:ip
+```
+
+#### Config dnsmasq
+```bash
+server=/example1.com/127.0.0.1#5353
+ipset=/example1.com/myset
+server=/example2.com/127.0.0.1#5353
+ipset=/example2.com/myset
+server=/example3.com/127.0.0.1#5353
+ipset=/example4.com/myset
+```
+
+#### Config iptables on your linux gateway
+```bash
+iptables -t nat -I PREROUTING -p tcp -m set --match-set myset dst -j REDIRECT --to-ports 1081
+iptables -t nat -I OUTPUT -p tcp -m set --match-set myset dst -j REDIRECT --to-ports 1081
+```
+
+Now you can startup glider and dnsmasq, the whole process:
+1. all dns requests for domain example1.com will be forward to glider(:5353) by dnsmasq
+2. glider will forward dns requests to 8.8.8.8:53 in tcp via forwarders
+3. the resolved ip address will be add to ipset "myset" by dnsmasq
+4. all tcp requests to example1.com will be redirect to glider(:1081)
+5. glider then forward requests to example1.com via forwarders
