Dirmngr and proxy

I have a network where all outgoing traffic must pass through a proxy server. 
The proxy server, 192.168.1.4, runs both an http proxy at port 3128 and an 
LDAP proxy (slapd) at port 389.

Dirmngr on a client is running:

/usr/pkg/bin/dirmngr --daemon \
    --http-proxy http://192.168.1.4:3128 \
    --ldap-proxy 192.168.1.4

When I try a test signing the uses certificate with an http crlDP, I see an 
outgoing message on 192.168.1.4 from the client to 192.168.1.4 that's blocked 
by the firewall.

What am I doing wrong?
