Re: OT (sort of): Best current practise for open access points ?

2004-12-08 Thread Volker Kindermann
Hi Peter, Message Submission Agent - it is SMTP but on a higher port, and is intended (as I understand it) for traffic from submitters - this means you can force SMTP AUTH etc. Allowing outbound 25 is just asking for spammers to waste bandwidth and get my IPs blacklisted. ok, it's not too hard

Hi Peter, I think what I want things like blocked outbound port 25 traffic, while allowing MSA, what is MSA? blocking common outbound virus traffic, To distinguish virus traffic from normal traffic you need some sort of application level gateway like squid for http traffic or an MTA for mail

Hi Siju, The Port 113 was opened because the PF FAQ asked to open it for SMTP Auth/Ident (TCP port 113): used by some services such as SMTP and IRC. ICMP Echo Requests: the ICMP packet type used by ping(8). I know that this is in the pf faq but I don't think that you really need it. I

redefine macros for authpf.rules???

2004-01-25 Thread Volker Kindermann
Hi, I'm just making my first experiences with authpf (OBSD 3.4 release) and found something strange: do I have to redefine macros in /etc/authpf/authpf.rules that are already defined in /etc/pf.conf (with anchor authpf at the end of pf.conf)? I tried to use macros such as $ext_if but while

Hi Trevor, As I don't have a PPPoE setup to work with, I did my own testing with just tun0, and saw the spin effect. Below is a patch for if_tun.c, which fixed the problem I observed. I'd like to know if it fixes pppoe queueing for anyone brave enough to try patches from me. it works

Queuing does not currently work with tun(4)/pppoe. I have spent one whole night playing w/ different options/config files to get empty ackpri to work on my ADSL link (I am using pppoe on the gateway itself). I've also played w/ different queuing schemes etc. 'pfctl -vvsq' still shows all
