Im trying to set up a network like this:
(IPs changed to protect the guilty)
1) Anyone wanna share the Landmines for the V.35 move?
2) How can I get SKIP on FreeBSD 2.2.6 to "de-skipify" incoming
skip traffic from , oh, say 156.46.1.1 on the net going to
the no-skip-unix box at 204.107.138.114 AKA 192.168.1.6?
3) Instead of ppp alias doing the NAT/IP Masquerading/aliasing,
how can I have natd do the NAT/IP Masquerading/aliasing work for me?
modem to net via tun0/ppp. Will be moving to a V.35 interface
| in 1-2 months.
+-----------------+
| Freebsd 226 | 204.107.138.113/28
+-----------------+
| ed0 interface 192.168.1.254
|
+-----------------------------------+
| 192.168.1.6 | 192.168.1.31
| would like it to be | would like it to be
| 204.107.138.114 to da net | 204.107.138.115 to da
+-----------------+ +---------------------+ net
| Unix box that | | NT box that can run |
| can not run SKIP| | SKIP |
+-----------------+ +---------------------+
What I have gotten working:
1) SKIP and NT. (instructions for how in next post to skip-list ok?)
2) ppp alias function (thus letting the unix/NT box to be seen)
What Hasnt worked for me:
1) ifconfig ed0 192.168.2.6 netmask 255.255.255.255 alias then tying
to tell natd to do redirect_address 192.168.1.6 192.168.2.6 didnt work.
2) ip-filter/ipnat. Got it compiled, but wouldnt NAT for me.
