I'm probably missing something that will be completely obvious to
someone else.

Around line 173 (in my workspace) is
            # Redirect system DNS to Tor's DNSport
            daddr 127.0.0.1 proto udp dport 53 REDIRECT to-ports 5353



but I thought that 
             outerface ! lo mod owner uid-owner i2psvc {
                 @if $use_i2p proto (tcp udp) ACCEPT;
             }


would allow DNS resolution. When it didn't, I explicitly ACCEPTED DNS
requests with

+                @if $use_i2p proto udp dport domain ACCEPT;
                 @if $use_i2p proto (tcp udp) ACCEPT;


because I thought that would override the redirect around line 173, but
DNS requests made by the i2psvc user still get redirected to the
TorDNS port. Since the explicit DNS exception didn't do what I
expected it to, I removed it.

Will re-read, thanks.
