Chris,


Another interesting observation occurred when testing egress from my LAN and router with various SRC IPs. My LAN is configured with a SNAT and IP/Rules to use 44.60.44.128 for traffic from a certain LAN SRC IP is set on the client.


* With my usual SNAT setting of SRC 44.60.44.128 - ping DOESN'T WORK
* When pining from the router with 44.60.44.1 and changing the LAN SNAT rule to also use SRC 44.60.44.1 - ping WORKS


root@OpenWrt:~# ping -c 5 1.1.1.1 -I 44.60.44.1
PING 1.1.1.1 (1.1.1.1) from 44.60.44.1: 56 data bytes

--- 1.1.1.1 ping statistics ---
