A lot many individuals run TOR exit nodes, but I never hear about people running their own I2P outproxies. Is it really hard to host, or is there some other reason? I thought that if you could run a TOR exit node I’d think you’d be just fine running an I2P outproxy.
Running more outproxies will help in bridging torrents from the clearnet to I2P, which would be a very good move considering the crackdowns on torrents right now. Companies even want to involve civilians into their lawsuits in Sweden now, making the need for privacy/anonymity even more important when torrenting, which I2P provides.

You can do multihoming, might be the easiest thing to do for a service: https://geti2p.net/spec/proposals/140-invisible-multihoming
Multihoming is a pretty simple way of load balancing and i think the way it works is the last router to announce is the one that’s used, so it should cycle through all routers periodically.
It’s also used to place i2p routers hosting a service in multiple places so it makes correlation attacks (ex downtime at exact time of a known electric outage in an area) more difficult.
Backend setup for your service
If we have a service like an http proxy service or a website available on port 6000, and 2 i2p routers, they’d both need access to that port. An outproxy may do this with port forwarding from a clean outernet connection(s) going through their proxy setup ex privoxy/haproxy/tinyproxy dns. They’re less worried about correlation attacks so the routers may be all or mostly in one area using port forwarding over lan or VM’s. A website that’s concerned about correlation attacks may have separate instances of the website running on each router in different areas, with the website’s backend syncing with the other routers in the background through other methods such as an encrypted lease-set.
Router setup
Each router needs the same exact key for the actual .i2p address. The easy way to do this is in the java router (i2p+ is good for this, install guide/official site go to service tunnels > make new server http tunnel, enter the port 6000, give it a name like “Outproxy”, private key file a name like “outproxy.dat” and make sure optimize for Multihoming is on.
Other recommended additions in your tunnel config
Then save and start, key file is generated.
Copy key file and a tunnel config file
Locations for .config file and key (.dat):
/i2p/.i2p/outproxy.dat/i2p/.i2p/i2ptunnel.config.d/XX-outproxy-i2ptunnel.configThen copy the key and config files to the other i2p routers in the same locations. Shouldn’t need to go through setup with the config file present. Most important is it has the same key file, so they’ll all use the same address.
Thanks, saved
