"Network: SymmetricNAT" problem

Post by AntibodyMama »

OS: MX Linux
i2p version: 2.5.2-0-1ubuntu1
i2p status: looks like it's working fine and i can visit i2p websites such as this one

I2P Network Peers:

Active: 25 / 156
Fast: 12
High capacity: 30
Floodfill: 81
Known: 302

I am using a VPN and i configured it requesting port forwarding and got a port.

I have the firewall turned on by default on my router.

UPnP is enabled by default on my router.

Still i am getting that "Network: SymmetricNAT" error !

I thought about setting up port forwarding on my router and these are the settings in my router

Name: I2P
Protocol: TCP or UDP
WAN Connection: INTERNET
WAN Host IP Address: <empty>
LAN Host: <my_computer's_mac_address>
WAN Port: <the_port_given_to_me_by_the_vpn>
LAN Host Port: <UDP_port_got_from_http://127.0.0.1:7657/confignet_>

I restarted my router now and i got "Network: Firewalled" instead of "Network: SymmetricNAT".

Does everything looks fine ? is that the correct configuration ?

I have an option in the VPN interface to exclude apps or IP addresses

But i cannot find which i2p app to exclude, which file.

I'd recommend looking for programs in C:\Program Files\i2p, more specifically i2p & i2psvc.
Maybe look into C:\Program Files\Java\[insert version here]\bin too if you're using Java I2P.

I2P runs on java, so maybe exclude the java vm program? (see in htop or similar process manager, the full path to it, if you need)
Excluding IP is not possible because there is no fixed ip of i2p network, it's p2p.

The OP said they're using linux, not windows

Oh my apologies. I must have skimmed the message.

Thanks for your replies.

I have switched to i2pd cuz its written in C++ and faster, also one binary easier to deal with.

This is what i see in the web console of i2pd
https://ibb.co/0Fgyg5N

This is the state when:
1. The i2pd binary (/usr/bin/i2pd) is excluded in the VPN app.
2. The firewall is turned on in my router.

I think the i2p java app was showing way too less routers.

I think i am stuck with this word "Firewalled" in i2pd as you see above in the picture. i2pd seems to work fine and i am accessing websites well. I don't know if there is a problem that i don't know about or if the router is not running at it's full functionality.

When i tried turning off the VPN and also turning off the firewall in the router, i also got "Firewalled", like WTF.

Thanks for reading this.

I sit behind ISP's NAT (that is to say, I do not have a public IP). My i2pd works just fine. Says Firewalled.
I still get transit. So it's not such a big deal, you can live with that.

Check if you really are accessible (e.g. canyouseeme, but idk if it actually works, might have to start a network service on that port)
