This script is a fork of Xentrk great job work.
Its work with OPENWRT after a good install you can use 2 ipset defined into firewall or load-balanced rules

Selectively route Netflix traffic to the WAN interface, or one of the five OpenVPN clients, on Asuswrt-Merlin firmware.
Since January 2016, Netflix blocks known VPN servers. This project was originally developed to bypass the OpenVPN client for Netflix traffic and route it to the WAN interface. The scripts now provide the ability to route Netflix traffic to an OpenVPN Client if desired. This can be accomplished by editing the $FWMARK parameter in the iptables commands inside the create_routing_rules function. If you want a VPN provider who can circumvent the Netflix VPN ban, see my blog post Why I use Torguard as my VPN Provider to learn more.
Netflix hosts on Amazon AWS servers. As a result, Amazon AWS domains in the US are also included.
There are two selective routing scripts used in this project. Each one uses a different method to collect the IPv4 addresses required for selective routing. Both scripts use the features of IPSET to collect IPv4 addresses in IPSET lists and match against the IPSET lists.
IPSET_Netflix.sh collects the IPv4 addresses used by Netflix from https://ipinfo.io using the Autonomous System Number (ASN) assigned to Netflix. Amazon AWS supplies the list of IPv4 addresses in the json file at https://ip-ranges.amazonaws.com/ip-ranges.json
Only the Amazon AWS US Regions are extracted from ip-ranges.json. As a result, the script will also route all Amazon AWS traffic bound for the US, including Amazon Prime traffic, to the WAN interface.
IPSET_Netflix_Domains.sh uses the IPSET feature built into dnsmasq to dynamically generate the IPv4 address used by Netflix and Amazon AWS dynamically. This approach can be useful when your ISP is using the Netflix Open Connect Network.
- Installation of entware. The /opt/tmp directory on entware is used to store the files containing the IPv4 addresses for the IPSET_Netflix.sh script and the backup IPSET list file for the IPSET_Netflix_Domains.sh script.
- The entware package jq is required by the IPSET_Netflix.sh script. jq is a json file parser. To install jq, enter the command
opkg install jqon the command line. - ipset version 6. To confirm the version you have installed, type
ipset -v - OpenVPN Client Settings:
- set Redirect Internet traffic to Policy Rules or Policy Rules (Strict)
- dnsmasq is bypassed when Accept DNS Configuration is set to Exclusive. I recommend setting Accept DNS Configuration to Strict as a solution. In the Custom Config section, specify a DNS server of your choice using the command
dhcp-option DNS xxx.xxx.xxx.xxxwhere the xxx's are a DNS server of your choice. For example:dhcp-option DNS 1.1.1.1
Autonomous System Numbers (ASNs) are assigned to entities such as Internet Service Providers and other large organizations that control blocks of IP addresses. The ASN for Netflix is AS2906.
This script will:
- Create the IPSET lists x3mRouting_NETFLIX and x3mRouting_AMAZONAWS
- Obtain the IPv4 addresses used by Netflix using AS2906 from ipinfo.io.
- Add the Netflix IPv4 address to the IPSET list x3mRouting_NETFLIX
- Parse the Amazon AWS json file using the jq entware package for IPv4 addresses used by Amazon in the US Region
- Add the Amazon IPv4 address to the IPSET list x3mRouting_AMAZONAWS
- Route IPv4 addresses in IPSET lists x3mRouting_NETFLIX and x3mRouting_AMAZONAWS to the WAN interface

IPSET_Netflix_Domains.sh uses the feature of ipset in dnsmasq to dynamically generate the IPv4 address used by Netflix and Amazon AWS dynamically. The script will create a cron job that will backup the IPSET list at 2:00 am. The backup will be used to restore the IPSET list upon system startup.
This approach can be useful when your ISP is using the Netflix Open Connect Network. The domain names used may vary by region. As a result, you will have to do some analysis to determine the domain names Netflix is using if the domains included in the script do not work for you. Below are the list of domain names used in the script.
ipset=/amazonaws.com/netflix.com/nflxext.com/nflximg.net/nflxso.net/nflxvideo.net/x3mRouting_NETFLIX_DNSMASQ
The x3mRouting_NETFLIX_DNSMASQ entry is the name of the IPSET list. The script will place the line in /etc/dnsmasq.conf.add if it does not exist.
To determine the domain names, follow the install instructions to download the script getdomainnames.sh to /jffs/scripts/getdomainnames.sh. Navigate to the dnsmasq log file directory. My dnsmasq.log file location is /opt/var/log.
Turn off the OpenVPN Client so all of your network traffic will traverse thru the WAN. Navigate to the dnsmasq log file directory /var/log. Type the command to start capturing domains used by Netflix:
tail -f dnsmasq.log > Netflix
Now, go to the device you are watching Netflix from. If you are streaming from your PC or laptop, close out other applications to minimize collecting domain names for non-Netflix traffic. Navigate around the Netflix menu options and watch several videos for a few minutes each to generate traffic and log entries to dnsmasq.log.
When done generating Netflix traffic, press ctrl-C to stop logging to the /opt/var/log/Netflix file. Run the getdomainnames.sh script, passing the file name and IP address of the device you were watching Netflix from. For example:
. /etc/getdomainnames.sh Netflix 192.168.1.20
This will create a file called Netflix_domains in the /opt/var/log directory. Open the file in an editor to view the domains names collected when watching Netflix. The next step is to desk check the file for domains not related to Netflix. These are domains generated by other applications on the LAN client you streamed Netflix from. Once you have narrowed down the domains, the next step is to update the ipset= references in the IPSET_Netflix_Domains.sh script using the domain names you captured. However, do not use the fully qualified domain name. For example, the domain occ-0-1077-1062.1.nflxso.net would be entered as nflxso.net; Likewise, www.netflix.com would be entered as netflix.com. IPSET_Netflix_Domains.sh will copy the ipset=/ line to /etc/dnsmasq.conf.add
The nslookup <domain_name> command is useful in looking up IPv4 addresses associated with a domain. Once you have the IPv4 address, you can use the whob <IPv4 address> command to display more information about the domain to confirm if it is associated with Netflix, Amazon AWS or a CDN provider, such as Akamai. whob is an entware package. Install using the command opkg install whob

ipset -L x3mRouting_NETFLIX command will list the contents of the IPSET list x3mRouting_NETFLIX
iptables -nvL PREROUTING -t mangle --line will display the PREROUTING Chain statistics or packet information. This command is very helpful to validate if traffic is traversing the chain.
ip rule will display the rules and priorities for the LAN clients and the fwmark/bitmask created for the WAN and OpenVPN interfaces.
service restart_dnsmasq will restart dnsmasq. Run this command to restart dnsmasq after making changes to /jffs/configs/dnsmasq.conf.add.
This project uses the selective routing method espoused by Martineau on snbforums.com. His technical assistance and support helped to make this project possible. Martineau also provided the Chk_Entware function.
