Vuze proxy settings are the one topic in this series we cannot document from the client's own sources, because those sources are gone. The project wiki at wiki.vuze.com returns a 404, and the last release on the project's SourceForge page, Vuze 5.7.6.0, is from November 2017. What remains is a live website, a large install base from Vuze's years as one of the feature-heaviest clients, and a maintained fork. For a reviewer, the first finding about Vuze on a managed machine is therefore not about proxies at all.
The short answer for a reviewer
If Vuze is on a host you are responsible for, the recommendation is to replace it with BiglyBT. BiglyBT is "forked from the original project and is being maintained by two of the original developers", it released version 4.1.0.0 in May 2026, and its proxy documentation is the most thorough of any client we reviewed. Its installer, by the project's own statement, "contains no third party offers".
Everything else on this page is for the case where Vuze cannot be removed yet.
What the record shows
The facts we could establish, and their sources:
| Item | Finding | Source |
|---|---|---|
| Platforms | Windows, Mac, Linux | vuze.com |
| Last release | 5.7.6.0, files dated 2 November 2017 | SourceForge release folder Vuze_5760 |
| Documentation | Wiki returns 404 | wiki.vuze.com |
| Advertising | "No Ads" listed as a paid Vuze Plus feature, implying the free build shows ads | vuze.com comparison |
| Licence of current builds | Not confirmed | Open-source lineage (Azureus), but current terms unverified |
| Proxy behaviour | Not confirmed | Primary documentation offline |
Why an unmaintained client is a finding by itself
A torrent client parses files and network messages from strangers all day. A client without a release for nearly nine years has had no security fixes in that time that anyone can point to, and an asset-management or vulnerability team will usually treat that as disqualifying before anyone asks what the proxy does. The same reasoning appears in any vendor review: the threat and vulnerability management questions in our security questionnaire guide apply to the software on the host as much as to the proxy vendor.
There is a policy question as well. Before any client runs on managed infrastructure, someone has to confirm that BitTorrent is permitted on the network and that the content, a distribution image, an open-source release, an archive item, is lawful to share. On our side, peer-to-peer traffic for lawful content is fine on residential exits and on dedicated ISP and datacenter addresses that carry no traffic meter. Using a ProxyForge exit for unauthorised sharing is excluded by our acceptable use policy.
Why we will not publish Vuze menu paths
Older guides describe a proxy section in Vuze's connection options. BiglyBT documents a page at Tools > Options > Connection > Proxy Options that comes from the same Azureus-era code. It is likely that Vuze 5.7 has something similar. Likely is not verified, and a reviewer signing an egress statement needs the second. We will not present a Vuze menu path or Vuze proxy behaviour as fact, and we would treat any guide that does with caution unless it cites a source you can still open.
Limits that apply whatever Vuze does
If a Vuze install does proxy its peers, the network-side limits are the same as for any client on our gateways:
- A seeded torrent is metered on the way in and again on the way out, so plan with our gigabyte definition and cap seeding.
- Our SOCKS5 endpoints should be treated as TCP only, with UDP relay unverified, so DHT, UDP trackers and uTP will not work through ProxyForge. An HTTP proxy cannot carry UDP.
- A proxy does not encrypt traffic, and whatever the client sends outside it shows the machine's own address.
- For copyright exposure a proxy is the wrong instrument; qBittorrent's documentation, for one, points such users to a VPN.
If Vuze has to stay for now
Measure rather than configure from memory. With the proxy set in the client and a lawful torrent running, capture on the machine and hide the proxy connection:
sudo tcpdump -ni any 'not (host PROXY_IP and tcp port PROXY_PORT) and not port 22 and not net 127.0.0.0/8'
On Windows, Wireshark with not (ip.addr == PROXY_IP and tcp.port == PROXY_PORT) does the same. Anything that remains, TCP to peer addresses or UDP datagrams to many destinations, left without the proxy. Write the result into the review as measured behaviour of that specific build, and set a removal date.
Moving a Vuze install to BiglyBT
Plan the move as a fresh install rather than an upgrade. Install BiglyBT from the project's own release page, re-add the torrents you still need to seed, and configure the proxy from BiglyBT's documentation rather than by copying settings across, since its wiki now describes exactly which traffic each option covers. Our BiglyBT guide walks through it, including the peer-source and DHT settings its wiki says to change. Then remove Vuze and record the change.
Review checklist
- Vuze version on the host recorded, with the 2017 release date noted
- Removal planned, with BiglyBT or another maintained client as the replacement
- Until removal: BitTorrent use approved and content source recorded
- Until removal: capture attached showing what the build sends outside the proxy
- No Vuze menu path or behaviour cited in the review without a primary source
