One again, I am having problems with pppd, gateways, and routing.
I use FreeBSD-2.1-RELEASE on a machine to dial up my ISP. It is
also connected to our local network. I have pppd working fine.
I can access the Internet from the FreeBSD machine without any
problems. The problem that I am having is trying to use the
FreeBSD machine as the gateway for the other computers on the
local network (about 5 other machines).
Here are my IPs that I use: 205.246.81.113->205.246.81.127.
There are 15 of em. I am using 255.255.255.240 for my netmask
on all the machine on the local net. I have my FreeBSD box (athena)
using 205.246.81.113 for ed1 and ppp0. The terminal server that
pppd connects to always gives me 205.246.81.113:205.246.83.35.
All the other machines (Win95, WinNT, and 3.11) machines use
205.246.81.113 (athena) as the gateway. Should I be using the remote
ip that ppp0 uses (205.246.83.35)? (I don't think so, since it
is 83.35 not in 81.)
Here is some of my sysconfig that related to routing and gateways:
# Set to the name of your host - this is pretty important!
hostname="athena.mycrowynn.com"
# Set to the NIS domainname of your host, or NO if none
defaultdomainname=NO
...
network_interfaces="ed1 lo0"
ifconfig_ed1="inet 205.246.81.113 netmask 255.255.255.240 link1"
ifconfig_lo0="inet localhost"
...
static_routes="multicast loopback"
route_multicast="224.0.0.0 -netmask 0xf0000000 -interface ${hostname}"
route_loopback="${hostname} localhost"
...
# Set to the host you'd like set as your default router, or NO
defaultrouter=NO
# These are the flags you'd like to start the routing daemon with
routedflags=-q
...
# If you want this host to be a gateway, set to YES.
gateway=YES
# Set to YES if you want to run gated
gated=NO
And here is my netmask -rn (ppp0 is up here):

OK the problem:
My apollo machine (Win95) has an ip 205.246.81.115. Netmask for apollo
is 255.255.255.240, and the gateway is the FreeBSD box (athena)
205.246.81.113. I can ping any machine on the local net. If I use
tracert -d to access a host outside (say ftp.cdrom.com), It will give me:
D:\WIN95>tracert -d 192.215.191.11
Tracing route to 192.215.191.11 over a maximum of 30 hops
1 2 ms 1 ms 1 ms 205.246.81.113
2 * * * Request timed out.
3 * * * Request timed out.
4
D:\WIN95>
The problem seems to be that FreeBSD is not routing the address from
ed1 to ppp0. I had the same setup for FreeBSD-2.0-RELEASE and some
2.1-SNAPS that worked fine. (BTW, I did not compile in the GATEWAY
option in the kernel, some told me it was not used anymore.)
Any ideas, or help???
