Merhaba herkese

web server ve email server onunde ids ve firewall icin bir yapi gerekiyor.
bu kullanimda iki adsl hatti icin nasil bir kullanim yapilmasi daha iyi olur?
ids icin snort mu onerirsiniz yada donanim firewall olarak pix, checkpoint, netscreen yada openbsd tabanli i-bekci (www.i-bekci.com) nasil olur?

32 mb ramli bir 1721 router imiz var.
halihazirda 1 mbit leased line baglanti uzerinden isp ye baglanip internete cikiyoruz.
buna ilaveten bir adet ethernet interface daha ekleyip ona da 8mbit bir wireless baglanti baglamayi ve igrp veya eigrp ile bunlari load sharing uzerinden calistirmayi hedefliyoruz. sizce calisir mi yoksa ram i arttirmak veya router i degistirmek gerekir mi dersiniz?
