Hi, Whilst doing some QA work on XORP on my desktop, which has fxp0 and msk0, fxp0 got totally hosed. I was running PIM-SM and IGMPv2 router-mode on the box at the time. I wonder if this is related to the problems with fxp multicast transmission I saw back in April. I'm a bit concerned about this as fxp is still a very widespread and useful network chip. I...

Hello, after upgrading my system from 7.1-RELEASE to recent RELENG_7 I noticed stalled network transfers in certain cases. I have an Intel PRO/100 ethernet adapter (card=0x00408086 chip=0x12298086 rev=0x0c). In general networking works fine. I can ping hosts, surf on websites and so on. But if I send large files (>1 MB) to my server the transfer stalls after a few kilobytes. This concerns FTP

[ -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

First machine to experience the problem was a single proc PIII-650 with 512M and Adaptec 2940UW, one fxp, doing a backup via scp, after 10 megs or so starting giving fxp0 timeout errors and dropping the connection (host was not pingable and dropped all arp entries).

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

...on another machine on a public IP, I'm not getting any routing, I can't even ping it from the same machine ...

But i have a problem with internet in this jail. I can log in to this jail through ssh or ftpd but i can't connect to the internet. I try to set up some kind of nat but it doesn't work. Can anybody help me

Hi, I plan to connect to remote Asterisk that will terminate calls to ISDN primary channel. I'd certainly like to secure this type of service, so would kindly ask for any advice on how to secure this authentication as much as reasonably possible. Since there is long IP route I guess VPN will take too much additional bandwidth... Regards, Robert.
