WAN Gateway IP reverse order on 1.13.X
Posted: Fri Sep 03, 2021 4:52 pm
I recently moved two TP-Link Archer routers to 1.13.X, using the builds available at https://lantisproject.com/gargoyle_custom/1.13.x/. Thanks for those, btw.
I have noticed some unusual behavior with regard to the WAN Gateway IP that appears in the WAN section of the Status page. These routers are connected to SB6190 modems; an A7 v5 and C7 v2 connected to Xfinity/Comcast and Suddenlink/Altice, respectively. Everything generally seems to be working fine, but I couldn't understand why the WAN Gateway IPs for both appeared as 1.x.x.x .... I mean, that would be an IP address somewhere in East Asia, yes? And then I realized ... the WAN Gateway IPs were the same as the WAN IP Addresses on both devices (minus the last octet, of course), but in reverse.
As an example (using bogus data), the WAN section of the Status page looks much like this:
WAN IP Address: 97.247.346.16
WAN Netmask: 255.255.252.0
WAN MAC Address: E7:E8:C1:8B:A1:E4
WAN Gateway IP: 1.346.247.97
I couldn't find other documentation of this on the forums ... anyone else seeing the same?
