I've been running tor on my openwrt-based home router (along the lines of 'anonabox'), and I configured it as a non-exit relay, because I thought why not - every little helps, right? I set a very low bandwidth limit, but it was using most of the configured bandwidth, so I figured it was helping.
A few days ago I got an email saying my tor version was EOL, so I upgraded from version 0.3.2.10 to 0.4.1.5 (which required upgrading openwrt). Now tor is still working fine for me, but I don't see any network traffic when I'm not using it, so it is evidently not routing any third-party traffic any more. I don't see any errors in the log.
Is this (a) expected behaviour because the previous traffic was just a bug in the old version of tor, or (b) an indication that there is something wrong with my upgraded installation? Any suggestions about where I should look would be welcome.
I'm considering reconfiguring my system to be a bridge instead of a router, but I would prefer to sort out any possible problems with what I've got now, before making further changes.
