I recently had an ADSL connection installed, which gives me a dedicated
internet connection through a proxy. An unanticipated side-effect of
this is that I'm now having problems when I use ppp to dial into work...
apparently due to the routing tables not being correct.
Here's what I have set up prior to invoking pon:
----------
eth0 Link encap:Ethernet HWaddr 00:10:4B:27:E5:5B
inet addr:10.0.0.21 Bcast:10.255.255.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:179677 errors:0 dropped:0 overruns:0 frame:0
TX packets:94941 errors:0 dropped:0 overruns:0 carrier:0

127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 10.0.0.21 0.0.0.0 UG 1 0 0 eth0
----------
As you can see, I have a default gateway configured, which is a
requirement for the ADSL connection. After using pon to establish the
ppp connection, I have the following:
----------
eth0 Link encap:Ethernet HWaddr 00:10:4B:27:E5:5B
inet addr:10.0.0.21 Bcast:10.255.255.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:16 errors:0 dropped:0 overruns:0 frame:0

168.166.225.14 * 255.255.255.255 UH 0 0 0 ppp0

127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 10.0.0.21 0.0.0.0 UG 1 0 0 eth0
----------
At this point I'm not able to successfully ping any of the systems at
work, presumably because the packets are being routed to the gateway.
I've tried "route add -net 168.166.0.0 netmask 255.255.255.255 ppp0",
but then route shows that a host route was added rather than a network
route. If I play with the netmask (like making it 255.255.255.0) I can
get a network route added, but either way I'm still not able to ping
anything through that interface.
I'd appreciate it if someone would point out what sort of routing entry
I need to setup in order to make this work. I'm running an up-to-date
slink system with kernel version 2.2.1.
Thanx!
