SubjectRe: weird routing - 2.0.36 bug?
Date
From
In article <Pine.GSO.3.96.990514122750.17102B-100000@ext1> you write:
> None of the HOWTOs and O'Reilly guides indicate that this problem is even
> possible. :) This is on kernel 2.0.36. Maybe a routing bug?

(the other message you included by mistake indicates that ppp over ssh
is recommended in an O'Reilly book. Horror. Do you get decent
performance out of that, or rather frequent hangs? If the latter,
switch to CIPE. ;-)

Why do you assign a transit address to the ppp device? And why the
alias device? That looks fishy to me. It should be enough to do this:

Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.1.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
10.10.10.254 0.0.0.0 255.255.255.255 UH 0 0 2 ppp2
207.15.208.16 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
10.0.1.0 0.0.0.0 255.255.255.0 U 0 0 182 eth0
10.10.10.0 10.10.10.254 255.255.255.0 UG 0 0 4 ppp2
0.0.0.0 207.15.208.16 0.0.0.0 UG 0 0 824 ppp0

where .254 is the address of the VPN router on both the ethernet and
the VPN device. I.e. it looks like this
