Ko se sprašuješ o firewallu in usmerjevalniku… / When you are asking about what kind of firewall and router to use…

Monday, January 1st, 2007

V zadnjem času sem kar precej časa posvetil dvema odprtokodnima firewalloma/routerjema, m0n0wall-u ter pfSense-u. Celotna mreža kiWi-Fi network je postavljena na m0n0wallu. Obe zadevi delujeta super tudi v specifičnih režimih delovanja (transparent firewall, dodatni programski paketi (pfSense) …)

In the past weeks I spent some time to check the two opensource firewall/router programs: m0n0wall and pfSense. The kiWi-Fi network infrastructure is based on m0n0wall. Both produts work perfectly even in complex and specific environment (transparent firewall, extra packages (pfSense) …).

Že večkrat so me ljudje spraševali o znanih težavah – preveliki količini sej (še posebej ob uporabi raznih *donkey *mule in podobnih P2P programih). Za vse tiste je primeren spodaj naveden članek. “Računica” pa je nakako takšna: 32MB RAMa = 30000 sej. 🙂

Some people asked me about the known troubles using low cost routers – too many sessions (when using *donkey and *emule like p2p programs). For all that have questions regarding this problem there is a link below. The calculation is quite simple: 32MB of RAM = 30000 sessions. 🙂
