[gabox]

Hi, I am newbie on world Asus router. I have a rt68u so im very satisfied with it. My doubt is following about routing table. I used my Asus router behind a isp modem bridge. I am a little confusing about 192.168.1.1 i dont know about it ?? and i dont understand on terminology routing table. Thanks a lot for your time.

Lan=192.168.2.0
Wan=179.41.x.x

GUI:
Destination Gateway Genmask Flags Metric Ref Use Type Iface
179.41.x.x * 255.255.255.255 UH 0 0 0 WAN0 ppp0
192.168.2.0 * 255.255.255.0 U 0 0 0 LAN br0
192.168.1.0 * 255.255.255.0 U 0 0 0 MAN0 eth0
default 179.41.x.x 0.0.0.0 UG 0 0 0 WAN0 ppp0
default 192.168.1.1 0.0.0.0 UG 1 0 0 MAN0 eth0

Your ISP modem probably runs a DHCP server, so the router obtains a lease from that, in addition to the ppp session that routes your Internet access.

You should disable DHCP in your ISP modem if you set that Asus router create PPPoE connection....

It's not ideal, you'd normally want to disable the DHCP server on your modem, but otherwise it shouldn't cause any issue since your LAN uses 192.168.2.xxx.
