kvas2-go

Better implementation of KVAS

Roadmap:

• DNS Proxy
• IPTables rules to remap DNS server [1]
• List loading/watching (temporary)
• IPSet integration
• Listing of interfaces
• IPTables rules to IPSet [2]
• HTTP API
• HTTP GUI
• Getting readable names of interfaces from Keenetic NDMS
• HTTP Auth

[1] Example

KVAS2_DNS_PORT=7548
iptables -t nat -I PREROUTING 1 -p udp --dport 53 -j REDIRECT --to-port $KVAS2_DNS_PORT

[2] Example

IPSET_TABLE=kvas2
MARK=1
TABLE=100
INTERFACE=ovpn_br0
iptables -t mangle -A PREROUTING -m set --match-set $IPSET_TABLE dst -j MARK --set-mark $MARK
ip rule add fwmark $MARK table $TABLE
ip route add default dev $INTERFACE table $TABLE
iptables -t nat -A POSTROUTING -o $INTERFACE -j MASQUERADE
