I have a brand new LFS 7.3 system that boots with no errors that I know
about. When I ping any IP address outside the LAN I get a 'Destination Host
Unreachable' error. I have an AT&T Uverse modem that connects me to the
internet. There is a TP-Link modem wired (ethernet) to the Uverse modem.
The TP-Link modem is the LAN controller (because it has faster wireless).
These IP addresses are from the TP-Link modem:
- LAN IP: 192.168.0.1
- WAN IP: 99.59.207.33
- Gateway: 99.59.204.1
A ping to the LAN IP and another computer on the LAN will work. This is a
sample of the error received when pinging any IP address outside the LAN:
PING 99.59.207.33 (99.59.207.33): 48 data bytes
60 bytes from 192.168.0.1: Destination Host Unreachable

The computer with LFS 7.3 is wired to the TP_Link modem. It is multi-boot
with these bootable distros, all of which can connect to the internet:
- Linux Mint 13 Mate
- Linux Mint 14 Mate
- Linux Mint 15 Mate
- Ubuntu 1304
- Kubuntu 1304
- Korora 18 KDE

Help?
