I'm trying to use a proxy with my wallet that requires authentication. I couldn't find a whole lot on this, but I was able to get the wallet to launch and connect to the network with the option "-proxy=proxyusername:proxypassword@proxyaddress.com:23". However, I'm not sure if it's working or not. How can I check the address my wallet is using, to check if it is using the proxy? Is there a console command or other way I can view it? Thanks.
Open Help > Debug Window and go to the peers tab. Click on one of the peers and in the area on the right of the window, it should show info about that peer. At the top it will say something like
37.187.151.83:8333 (node id: 5)
via 176.10.104.240:35174
The first ip address is the nodes ip address, the second, after the "via" is your external ip address. If this ip address matches your proxy's ip, then you are using the proxy correctly. If it doesn't then something is wrong.
