Access services hosted on a netqube

Hi, I am trying to create a configuration for i2p based services. I wanted to create something like:

irc_client->sys-i2p->firewall

the irc client would have qvm-firewall rules to only allow traffic on the one port, and point an irc client to the net-VM’s IP. sys-i2p runs the standard java router, with the tunnel for irc2p bound to 0.0.0.0.

I can see the netVM’s ip using ip route, and can ping it, but trying to connect pidgin to it fails (iv’e used it before to connect to i2p running in the same VM). Is there any info on how hosting services on a netVM for downstream qubes works? thank you in advance.
