Hi,
i have the following setup:
+-------------+ +-------+ +------------+
| | | DDWRT | | |
| Windooze7 | | WLAN | | Gentoo |
| | +---+---+ | |
+------+------+ | +-----+------+
| +------+-----+ |

During my Gentoo VM-Host Setup i ran into some networking issues.
They are solved by now, but i don't understand why the steps i had to take were necessary.
I did not get ICMP-Replys from Windooze if i pinged it from Gentoo.
I got ICMP-Replys from Gentoo when pinged from Windooze.
Windows was pingable and replyed to/from OpenBSD.
I did not try pings from WLAN to Windooze.
Why did i had to allow incoming ICMPv4 Packets on the Windooze Failwall? It did reply to OBSD pings, i don't get it.
