It was noted that both LinkingLion connections and Bitcoin Core connections via i2p and tor, by default, set their addresses to 127.0.0.1 for inbound connections and 0.0.0.0 for outbound connections. This differentiation underscores the technical setup where only outbound connections currently utilize a proxy as per the "BIP324 proxy scenario" graphic and associated slides provided.

The conversation further delves into the limitations and future tasks related to enhancing Bitcoin Core's connectivity. One significant limitation highlighted is the current inability to implement BIP-155 address serialization for TorV3, I2P, CJDNS within Bitcoin Core, which results in these addresses being represented as 0.0.0.0. This issue is documented in the Bitcoin Core codebase (bitcoin/src/net_processing.cpp), pointing towards a need for technical advancements to support more diverse address types effectively.

Despite the identified limitations, the email suggests an optimistic outlook for the implementation of BIP324, allowing for encrypted connections. It mentions that running a listening node with BIP324 is already possible with Bitcoin Core version 26.0+, indicating progress in this area. Moreover, there's an expectation that relevant alternative node implementations will adopt this standard, potentially before it becomes widespread among light clients.

Lastly, the email reflects on the practical utility of a reverse proxy for inbound connections. Initially considered from a technical perspective, further contemplation led to the conclusion that such a setup might not be crucial in practice. This is partly because the protocols in question (e.g., Tor, I2P) inherently provide encryption, suggesting that additional layers of proxying may not significantly enhance security or functionality for these connections.
