Hello,

If you are using user-level PPP, you can use its ppp.linkup features,
otherwise man isdnd.rc:
connectprog specifies a program run everytime after a connec-
tion is established and address negotiation is
complete (i.e.: the connection is useable). Isdnd
expects to find the program below the path
/etc/isdn which is prepended to the string speci-
fied as a parameter to this keyword. The programs
specified by connect and disconnect will get the
following command line arguments: -d (device) -f
(flag) [ -a (addr) ] where device is the name of
device, e.g. "isp0", flag will be "up" if connec-
tion just got up, or "down" if interface changed
to down state and addr the address that got as-
signed to the interface as a dotted-quad ip ad-
dress (optional, only if it can be figured out by
isdnd). (optional)
If you are dealing with the packet filter you should deal with it a bit more,
it would be better if it wouldn't need refresh every time. You should
specify your tun0 or isp0 interface, not their IP address. If you are using
user-level PPP, please take a look at its filtering features.
Good luck.
