Docker and iptables Estimated reading time: 4 minutes On Linux, Docker manipulates iptables rules to provide network isolation. The first rule is a rule which makes sure that all internal traffic on port 80 (from the router's subnet to the router's subnet) are not affected and continue to get processed normally. 0/8-j RETURN #重定向所有不满足以上条件的流量到redsocks监听的12345端口sudo iptables -t nat -A OUTPUT -p tcp -j REDIRECT --to-ports 12345 #12345是你的redsocks运行的端口,请根据你的情况替换它. Tale funzionalità, ormai già presente out-of-the-box in praticamente tutte le distribuzioni Linux con Kernel recenti effettua un mark di tutti i pacchetti in arrivo e ne riscrive l’ip sorgente prima di mandarlo alle catene di INPUT. 0/24 The same logic applies to addresses used by the NAT box itself: this is how masquerading works (by sharing the interface address between masqueraded packets and `real' packets coming from the box itself). 0/16 -j RETURN iptables -t mangle -A V2RAY_MASK -p udp -j TPROXY --on-port 12345 --tproxy-mark 1 iptables -t mangle -A PREROUTING -p udp -j V2RAY_MASK. Please realize that this just gets the packets to the proxy;. iptables • Set firewall mark to enable special routing • Can use entire mark or a bit range and value • Only need 1 bit • Mark based on server port and host interface • Mark TPROXY for inbound transparent • Required for ATS to accept connection with foreign destination address • Redirect to ATSproxy port • Use ip6tables for IPv6. rules; etc/iptables/ip6tables. For real transparent proxying you need to use the TPROXY target (in the mangle table, PREROUTING chain). 2/32 -p tcp --dport 443 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3127 /sbin/ip rule add fwmark 1 lookup 100 /sbin/ip route add local 0. On their page regarding transparent proxies you can see that there is a way to write iptables rules such that udp traffic is forwarded to the transparent proxy. lsmod Module Size Used by nfnetlink_log 8037 0 nfnetlink 3489 1 nfnetlink_log fuse 69258 2 iTCO_wdt 5447 0 iTCO_vendor_support 1929 1 iTCO_wdt joydev 9727 0 snd_hda_codec_analog 79922 1 coretemp 6198 0 arc4 2007 2 kvm 392193 0 btusb 14804 0 bluetooth 301098 2 btusb pcmcia 46292 0 microcode 14465 0 psmouse 76175 0 iwl3945 55148 0 i2c_i801 11077 0 pcspkr 1995 0 serio_raw 5105 0 evdev 10136 13.

There's no obvious policy routing in Linux - you use iptables to mark interesting traffic, iproute2 ip rules to choose an alternate routing table and a default route in the alternate routing table to policy route to the distribution. 0/16 -j RETURN # 局域网网段 iptables -t nat -A PREROUTING -p tcp -j V2RAY # tcp 全部走 V2RAY 这个链 iptables -t nat -A PREROUTING -p udp -j V2RAY # udp 全部走这个链.
