+## Linux routing things
+
+
+#### same interface reply
+https://gmelikov.com/2018/02/27/linux-network-reply-interface-incoming/
+
+Long story short: local corporate server have 2 interfaces:
+
+1) Public Internet IP address (eth0)
+2) Local network IP address (eth1)
+
+By default Linux tries to reply on interface with default route (eth0 in this case), even if request came from different iface (eth1). Let’s fix it.
+We need to create an `ip rule` with IP adresses table and configure it for all interfaces:
+
+```
+echo 200 reth0 >> /etc/iproute2/rt_tables
+echo 201 reth1 >> /etc/iproute2/rt_tables
+ip rule add from <ip address of eth0> table reth0
+ip route add default via <gateway of eth0> dev eth0 table reth0
+ip rule add from <ip address of eth1> table reth1
+ip route add default via <gateway of eth1> dev eth1 table reth1
+```
