Once a PPP connection has been established and a corresponding interface
has been registered, should we be able to ping it from the machine on
which it resides?
We are having a major problem with our second PPP link to our ISP, in that
no data can get across the link; we have just noticed that we cannot ping
the local address. Instead, any packets sent to the interface disappear,
and are registered by ifconfig as RX errors:
charon:# ifconfig ppp6
ppp6 Link encap:Point-to-Point Protocol
inet addr:203.55.169.2 P-t-P:203.29.72.5 Mask:255.255.255.240
UP POINTOPOINT RUNNING MTU:552 Metric:1

charon:# ping 203.55.169.2

When the second PPP link is connected, our routing table looks thus:
charon:# netstat -rn
Kernel IP routing table

0.0.0.0 203.29.72.5 0.0.0.0 UG 0 0 16529 ppp1
(some routes thought to be irrelevant have been removed - they are dial-in
PPP links).
Any help will be greatly appreciated,
