8.0-BETA2 on soekris discarding packets?

Hi,

I'm trying 8.0-BETA2 on a 4511 soekris board, but found a problem.

Outgoing networking is fine, but it looks like incoming connections are
silently discarded. No firewall is configured. Here's a tcpdump of normal
outgoing DNS traffic (IP address of the soekris is 192.168.179.15):

listening on sis0, link-type EN10MB (Ethernet), capture size 96 bytes
10:33:50.053875 IP 192.168.179.15.23093 > ei.lan.domain: 45893+ PTR? 255.179.168.192.in-addr.arpa. (46)
10:33:50.055038 IP ei.lan.domain > 192.168.179.15.23093: 45893 NXDomain* 0/1/0 (109)
10:33:50.066917 IP 192.168.179.15.13890 > ei.lan.domain: 45894+ PTR? 9.179.168.192.in-addr.arpa. (44)
10:33:50.067834 IP ei.lan.domain > 192.168.179.15.13890: 45894* 1/1/1 (113)

And here's a dump of an incoming ssh connection:

listening on sis0, link-type EN10MB (Ethernet), capture size 96 bytes

Et cetera. No replies. This goes for all tcp ports, but ping works. nmap from another host says:

# nmap soekris

Anyone else seeing this?
