Hi,
My machine is on a /28 subnet in the range of 193.56.58.65-78. I have a PPP
address of 193.56.58.46 (in another subnet) pointing to a machine on the
side with a 193.56.58.33 address.
Giving:
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 193.56.58.65 netmask 0xfffffff0 broadcast 193.56.58.79
ether 00:00:c0:7c:66:48
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 193.56.58.46 --> 193.56.58.33 netmask 0xfffffff0
and:

Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 193.56.58.33 UGc 0 0 tun0

193.56.58.64/28 link#1 UC 0 0
224/4 link#1 UCS 0 0
When using IIJPPP, routing doesn't work at all:
258 [19:31] root@keltia:~# ping 193.56.58.33
PING 193.56.58.33 (193.56.58.33): 56 data bytes
^C
--- 193.56.58.33 ping statistics ---
15 packets transmitted, 0 packets received, 100% packet loss
It seems unable to cope with a subnetted network even if I define my
address in ppp.conf, I can't even ping its own interface 193.56.58.46:
250 [19:32] root@keltia:~# ping 193.56.58.46
PING 193.56.58.46 (193.56.58.46): 56 data bytes
ping: sendto: No route to host
ping: wrote 193.56.58.46 64 chars, ret=-1
ping: sendto: No route to host

brasil:

------------------------------------------------------------
Kernel PPP works fine with the same setup:
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 193.56.58.46 --> 193.56.58.33 netmask 0xfffffff0
282 [19:44] root@keltia:~# ping 193.56.58.33
PING 193.56.58.33 (193.56.58.33): 56 data bytes
64 bytes from 193.56.58.33: icmp_seq=0 ttl=63 time=177.546 ms
64 bytes from 193.56.58.33: icmp_seq=1 ttl=63 time=169.326 ms
Is this a bug in IIJ PPP ?
