Double NAT?

[krl69]

I might have a double nat problem on my lan. If I run a trace against e.g. vg.no I get:


1 <1 ms <1 ms 1 ms GT-AX11000-BD50 [192.168.50.1]
2 1 ms 1 ms 1 ms 192.168.10.2
3 9 ms 8 ms 8 ms 242.79-160-116.customer.lyse.net [79.160.116.242]
4 8 ms 8 ms 8 ms 219.213-167-114.customer.lyse.net [213.167.114.219]

6 7 ms 7 ms 7 ms lo.s2-g10-osl2.n.bitbit.net [87.238.63.8]
7 7 ms 7 ms 7 ms www.vg.no [195.88.54.16]

And if I run an ifconfig on my Asus router (AX11000 with Merlin), I get 2 LAN addresses:

br0 Link encap:Ethernet HWaddr xxxxxxxxxx
inet addr:192.168.50.1 Bcast:192.168.50.255 Mask:255.255.255.0

I can't find the address 192.160.10.2 anywhere, but it responds when I ping and stops when I take down eth0 or reboot the router. My ISP modem/router is set in bridge mode and connected directly to the WAN port of the Asus router.

Can anyone explain what this is?

Solved it!

Went into the ISP's config of their modem/router, turned off bridge, then went back in and turned off upnp, saved and set it back to bridge. Voila and eth0 shows the ISP address and not the LAN address of the ISP modem/router.
