# Connect through a proxy
 | 
						|
 | 
						|
Some corporate and university networks may require you to connect to Zulip
 | 
						|
via a proxy.
 | 
						|
 | 
						|
## Web
 | 
						|
 | 
						|
Zulip uses your browser's default proxy settings. To set a custom proxy just
 | 
						|
for Zulip, check your browser's instructions for setting a custom proxy for
 | 
						|
a single website.
 | 
						|
 | 
						|
## Desktop
 | 
						|
 | 
						|
{start_tabs}
 | 
						|
 | 
						|
{tab|system-proxy-settings}
 | 
						|
 | 
						|
{!desktop-sidebar-settings-menu.md!}
 | 
						|
 | 
						|
1. Select the **Network** tab.
 | 
						|
 | 
						|
1. Click **Use system proxy settings**.
 | 
						|
 | 
						|
1. Restart the Zulip desktop app.
 | 
						|
 | 
						|
{tab|custom-proxy-settings}
 | 
						|
 | 
						|
{!desktop-sidebar-settings-menu.md!}
 | 
						|
 | 
						|
1. Select the **Network** tab.
 | 
						|
 | 
						|
1. Click **Manual proxy configuration**.
 | 
						|
 | 
						|
1. Either enter a URL for **PAC script**, or fill out **Proxy rules** and
 | 
						|
  **Proxy bypass rules**.
 | 
						|
 | 
						|
1. Click **Save changes**.
 | 
						|
 | 
						|
{end_tabs}
 | 
						|
 | 
						|
## Additional tips for custom proxy settings
 | 
						|
 | 
						|
In most corporate environments, your network administrator will provide a
 | 
						|
URL for the **PAC script**.
 | 
						|
 | 
						|
The second most common configuration is that your network administrator has
 | 
						|
set up a proxy server for accessing the public internet, but URLs on the
 | 
						|
local network must be accessed directly. In that case set **Proxy rules** to
 | 
						|
the URL of the proxy server (it may look something like
 | 
						|
`http://proxy.example.edu:port`), and **Proxy bypass rules** to cover local URLs
 | 
						|
(it may look something like `*.example.edu,10.0.0.0/8`).
 | 
						|
 | 
						|
If either of those apply, you can skip the rest of this guide. If not, we
 | 
						|
document the syntax for **Proxy rules** and **Proxy bypass rules** below.
 | 
						|
 | 
						|
### Proxy rules
 | 
						|
 | 
						|
A semicolon-separated list of `protocolRule`s.
 | 
						|
 | 
						|
```
 | 
						|
protocolRule -> [<protocol>"="]<URLList>
 | 
						|
protocol -> "http" | "https" | "ftp" | "socks"
 | 
						|
URLList -> comma-separated list of URLs, ["direct://"]
 | 
						|
```
 | 
						|
 | 
						|
Some examples:
 | 
						|
 | 
						|
* `http=http://foo:80;ftp=http://bar:1080` - Use proxy `http://foo:80`
 | 
						|
  for `http://` URLs, and proxy `http://bar:1080` for `ftp://` URLs.
 | 
						|
* `http://foo:80` - Use proxy `http://foo:80` for all URLs.
 | 
						|
* `http://foo:80,socks5://bar,direct://` - Use proxy `http://foo:80` for
 | 
						|
  all URLs, failing over to `socks5://bar` if `http://foo:80` is
 | 
						|
  unavailable, and after that using no proxy.
 | 
						|
* `http=http://foo;socks5://bar` -  Use proxy `http://foo` for `http://` URLs,
 | 
						|
  and use `socks5://bar` for all other URLs.
 | 
						|
 | 
						|
### Proxy bypass rules
 | 
						|
 | 
						|
A comma-separated list of URIs. The URIs can be hostnames, IP address
 | 
						|
literals, or IP ranges in CIDR notation. Hostnames can use the `*`
 | 
						|
wildcard. Use `<local>` to match any of `127.0.0.1`, `::1`, or `localhost`.
