[ -netters, please Cc me or security@ with replies. ] I'm running into trouble integrating dynamic racoon-based IPSec into a network with ipfw and natd. I need to be able to allow VPN access from any address from authenticated clients. I've got the dynamic VPN working, with racoon negotiating SAs and installing SPs, but the problem is that I can't tell whether an incoming packet on the internal interface should go through natd or not. T...

I have setup natd, enabled logging with -l and it is working perfectly. However is there a more detailed log to see the translation tables. I need to log the ipaddress internal 172.*.*.* to the outside with what port is being used. natd just seems to log the statistics such as icmp=5 and so on. If natd does...

Hi. We just opened a gaming center and have chosen to run a FreeBsd box for our firewall. IPFW is configured at it's very basic running natd through rl0 and allowing any to any connections from the lan to the outer world. Natd controls access to the lan. We have a 6.0 mb/s ADSL net connection for all the gaming clients to use, however if a gamer starts downloading a file, that file takes precendence and causes everyone's pings...

I've been using ipfw for a while to create a router with NAT and packet filtering, but have never combined it with stateful filtering, instead using things like "established" to accept incoming TCP packets which are part of a conversation initiated from the "inside". I'd like to move to using keep-state/check-state to get tighter filtering and also to allow outgoing

hi i have a problem with my icmp, i have a router that performs nat. i cannot ping to internet hosts from more than one stations situated behind NAT at once. if i want to ping from another station i have to stop the ping that was initiated from the first host, and after a few seconds i can ping from another station.i've checked firewll and i have no ipfw rules that could stop icmp traffic.

I have a FreeBSD box acting as a firewall and NAT gateway I would like to set it up to transparently pass IPSec packets -- I have an IPSec VPN client running on another machine, connecting to a remote network. Is there a way to do this? I can't find any hints in the man pages.

Hi, I have a system with a 4.11 Kernel. Unless I'm doing something very wrong, there seems to be something odd with ipfw. Take the following rules: ipfw add 00280 allow tcp from any to any 22 out via bge0 setup keep- state ipfw add 00299 deny log all from any to any out via bge0 ipfw add 0430 allow log tcp from any to me 22 in via bge0 setup limit src-addr 2 ipfw add 00499 deny log

...rk this dog just don't hunt. > > Is there perhaps some part of this I'm missing? Workaround: Take a box inside the secure network and have it NAT mail & LDAP connections from the MPD'd range to the mail server. Then have your MPD'd users use that box. You can use ipfw+natd to do this; something like: natd -redirect_address ma.il.ser.ver 0.0.0.0 ipfw add divert 8668 tcp from mpd.ra.ng.es/bits to int.er.nal.ip \ 25,110,389 in recv enet0 ipfw add divert 8668 tcp from ma.il.ser.ver 25,110,389 to int.er.nal.ip in recv enet0 If resources aren't scarce, you could ev...

...st me or do others have a problem with the ATA-186 de-registering? Every couple of hours, if I don't make use of the ATA connected line, I find that I have to unplug and let the ATA reboot. After that it is good to go for awhile, but eventually I have to repeat the process. My ATA sits behind a NATd firewall, any ideas what might cause the de-registration? Kim C.

I feel I should know the answer to this, but I wanted to verify. I have a bunch of Windows PC's running Win 2K Pro, on three subnetworks. Two of the subnets are served by Unix (FreeBSD) boxes running NATD, but all are joined to a domain being run on a Win 2K Pro server in another building on the campus. So far I haven't joined the two Unix boxes to the domain. I'd like to experiment with setting one of the FreeBSD boxes up as a Primary Domain Controller to experiment with LDAP and roamin...

...lice rate to limit upload speed - but this is not particularly effective and also not really required, as the box is able to shape traffic in both directions. It is also a NAT box. Related, not but strictly to do with tc, is there any way of concisely and effectively logging connections between NATd users and external IPs? I need to be able to maintain a log which tells me that a certain user was connected to a certain remote host on a certain port at a certain time and date, for legal reasons. I realise this is a bit of a mammoth request, but I hope someone can help me. Many thanks in a...
