Interesting, the client shows :

CONNECTED(00000003)

Pflog shows  (this time 192.168.103.69 was used in place of 192.168.103.1):

1294126958.718778 rule 0/0(match): pass in on ed0: (tos 0x0, ttl 64, id
6708, offset 0, flags [DF], proto TCP (6), length 60)
    192.168.103.69.51472 > 192.168.103.62.443: Flags [S], cksum 0xb80b
(correct), seq 4218566242, win 5840, options [mss 1460,sackOK,TS val
5844054 ecr 0,nop,wscale 7], length 0

For tcpdump, there was no network communication. I guess it's close, but
not yet working.
