--0-4208400-1087975437=:11808 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Content-Id: Content-Disposition: inline hello there, Ive never done this before (and it may seem odd) but, id like to get your advice on how to configure a network with 2 outside interfaces. One interface would be connected to a cable modem and the other to an adsl modem. This is what i have so far. 1 cable connection 1 adsl connection 1 computer (running fbsd 5.2.1) 5 NICs the diagram i have attached is kinda what im thinking it would look like. Any advice would be great. I have compiled the following options into the kernel # Firewall IPFIREWALL options options TCP_DROP_SYNFIN options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=100 options IPFIREWALL_DEFAULT_TO_ACCEPT options RANDOM_IP_ID options IPDIVERT options IPSTEALTH options IPSEC set the following in rc.conf ifconfig_fxp1="DHCP" #*cable* ifconfig_fxp2="inet 10.0.0.1 netmask 255.255.255.0" ifconfig_fxp3="DHCP" #*adsl* ifconfig_fxp4="inet 10.5.0..1 netmask 255.255.0.0" # PPP CONFIGURATION - adsl #ppp_enable="YES" #ppp_profile="provider" #ppp_mode="ddial" # NAT CONFIGURATION #natd_enable="YES" #natd_interface="fxp1 fxp3" #natd_flags="-s -u -f /etc/natd.conf" # FIREWALL CONFIGURATION IPFW #firewall_enable="YES" #firewall_type="SIMPLE" #firewall_quiet="NO" I dont really know if im going about this the right way or not (or what im missing), but i think im going to end up confusing myself at some point. esp. when it comes to the firewall rules. so if you have some advice. id gladly listen/read. cheers (i hope this makes sense) ams Find local movie times and trailers on Yahoo!
