I2Pconsol stuck on testing whether UDP port is firewalled or not

Currently my I2P network configs are:

[UPnP Status]                   
(No tick mark) Enable UPnP to open firewall ports 

IP Configuration
Externally reachable IP address:
(tick)Use all auto-detect methods

IPv4 Configuration:
(Not no tick mark) Disable inbound (Firewalled by home network, ISP, DS-Lite, or carrier-grade NAT) 

IPv6 Configuration:
(tick) Prefer IPv4 over IPv6

Action when IP changes:
(tick) Laptop mode - Change router identity and UDP port when IP changes for enhanced anonymity (Experimental) 

UDP Configuration: skip not relevant

TCP Configuration
Externally reachable TCP port: skip not relevant

Externally reachable IP address:
Use auto-detected IP address (currently x.x.x.x) if we are not firewalled

Expected behavior: I2P should decide whether its firewalled or not.

It's hard to diagnose what the problem is for OP, but Peer Test for SSU2 is more reliable than for SSU1, as of 2.0.0, and there's numerous fixes in 2.1.0 that really cleans things up even more. I'm going to optimistically close this.

changed milestone to %2.1.0
