Hi,
I've been running ipchains to do masq'ing and fwd'ing for a while but the
rules were never very good. I had loads of problems whilst setting up but
managed to cobble something workeable together. I now want to set it up
properly. I know how to make the rules etc and I think I've got the rules
I want sorted. Could some one comment on the following and tell me what
you think I'm trying to achieve and if I'm missing anything out.
------------------------
Input Default - Deny (Deny Everything comming in)
ALL from 192.168.1.0 Accept (Allow anything coming over ethernet)
ALL from 192.168.2.0 Accept (As Above)
ICMP from 0.0.0.0 ppp0 Accept (Allow ping requests etc over modem)
SMTP from Demon 1 ppp0 Accept (Allow SMTP connections from isp's punt1)
SMTP from Demon 2 ppp0 Accept (Allow SMTP connections from isp's punt2)
Output Default - Accept (Allow output to anything?)
Forward Default - Deny (Don't Masq anything)
ALL from 192.168.1.0 MASQ (Allow any local connection to be masq'd)
ALL from 192.168.2.0 MASQ (Allow any local connection to be masq'd)
----------------------------
I *think* that should cover everything.
Thanks a lot in advance.
Andrew
