Hello,

I have:

# /sbin/ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

        address: 00:07:e9:82:d9:8f

        inet 62.48.88.70 netmask 0xffffffff broadcast 62.48.88.70

and:

$ netstat -anf inet

with noise clipped, and a default gateway of 62.48.88.65. I get the following curious result on a -current as of yesterday/Saturday:

Neither sshd nor sendmail accept a connection on the primary IP address, 62.48.88.67, but only on the other addresses. The symtom is, using tcpdump, that while connecting to the primary address, no SYN packet ever gets answered. The problem does not appear to happen with UDP packets.

Before that I ran the snapshot from August 22nd where this worked ok.

Do you need help?X

Some insight is very welcome!

Best,
