I have decided to try MikroTik's RouterOS on a virtual machine to evaluate it before buying a RouterBOARD. I fell in love with it instantly. It is just so immensely powerful and very easy (or at least straightforward) to setup with the GUI provided. Even though I finally decided to buy a RB750G, I would still like to have something similar for my ad-hoc virtual networks in VMware. Does any of you perhaps know of any similar operating system/software bundle designed for routers/firewalls and featuring a similar interface. RouterOS, while being fairly cheap, is a bit too expensive for such ad-hoc installations that tend to only be used for a brief while. So, I am looking for a free/open-source distributions. I have already tried m0n0wall [a fixed LAN/WAN model], pfSense [no IPv6 support] and OpenWRT [all but the most basic configuration needs complex CLI configuration], none of them being even remotely close to what I would want. So, ideally, I would want the OS to support: - an arbitrary number of network interfaces, each individually configurable - various VPN/tunneling protocols - Ethernet bridging - decent IPv6 support (RA, DHCPv6, static routes, RIPng) - routing protocols (RIP, BGP, OSPF) - a decent firewall (connection tracker, NAT&PAT, forwarding of arbitrary IP protocols, ...) OK, is this too much to ask? :) I would really like to know if there is something like this...
