Hello!
Well Im trying to make a firewall in a rather strange fashion.
+-------+
| cisco |---(slink)<--- pointopoint ethernet ---> (suse) ---> the rest
+-------+
slink == debian 2.1
suse == SuSE 6.1
The thing is this:
Cisco: it is a cisco router that I have no access to configure at all, it
put all packets on the net via it's ethernet.
slink: the machine that must be transparent and do proxy-arp of only (suse)
IP or permit some ports of (suse) be accesible from outside.
pointopoint: it's a direct connection between slink eth1 and suse
eth0(crossover patch cord). With kernels 2.0.* works, with 2.2.* cannot
configure the interface as pointopoint.
The rest. It is a masqerade net by (suse). Only to access the internet.
(suse) has a valid IP. slink also has a valid IP.
I need that slink route packets comming from eth0 going for (suse) to
(suse).
I need to access http, ssh, sftp of (suse) from internet, but from the
internal network i need to access internet in most services...
Things that I thought:
arp... but no doc could I find to help me do it, proxy-arp-subnetting is not
what I need. And 'arp -s $(suse)IP $(suse)MAC pub' didnt work.
ipfwadm... any help is welcome as I dont understand very well the
documentation nor the basics how works.
rinetd... could do something but ssh sftp didn't work, only work http
rinetd only redirect tcp ports not udp.
ipforward... same or worst as arp.
Any help is welcome.

BTW: how can I make my zipdrive work under kernel 2.2.* as module? in 2.0.*
works.
