I have searched through the archives and havent found an answer to my
problem, o here it is.
I am running RH 8.0 Kernel 2.4.19-8.5.27
Used Netfilter patch bridge-nf-0.0.7-against-2.4.19.diff
IPTABLES v1.2.6a
followed the instructions line for line in Firewalling for free.
Enabled 802.1b bridging and Netfilter options as well as IPTABLES firewall in the kernel config.
The Bridge works great packets go throught it no problem. eth0 0.0.0.0 promisc eth1 0.0.0.0 promisc bridge 127.0.0.1 promisc up
I am running Snort 2 and I see the traffice going from host to internet and Vice versa.
I have copied the IPTABLES Script from Firewalling for Free and added a few extra lines to suit my DNS Servers and different Web Servers.
IPTables doesnt seem to be doing anything I can scan using NMAP from my HOME PC. Iptables is Loaded at boot, and when i type iptable -L i see all my rules and chains, just as they appear in the docs.
Anyone have any ideas How I can get the IPTables portion to stop hackers from snooping around my network, I have also created rules that should stop the Slammer virus from getting in and messing up any servers that users may have forgotten to patch.
Any help on this is appreciated.
Thanx, Allan bigaldover@xxxxxxxxxxx
