+## 403 Errors
+
+The PSI development instance (<discovery.development.psi.ch>) is only accessible from restricted networks. Connecting from a disallowed IP address results in a 403 error:
+
+![Example 403 Forbidden Error]({% link assets/img/documentation/admin/403_forbidden.png %}){: .center style="border: solid #ccc 1px; padding:5px"}
+
+To solve this, you need to connect via an allowed system. The best way to set this up for operators is to configure a SOCKS5 proxy.
+
+## Intended audience
+
+This is intended for operators trying to test the ingestor against the development SciCat instance (<https://discovery.development.psi.ch>).
+
+## Prerequisites
+
+You will need ssh access to an allowed server. This will usually be the ingestor server, which should have been whitelisted by PSI already.
+
+
+## Start the proxy
+
+### SSH with the command line
+
+If you can SSH to the ingestor at the command line, starting a SOCKS5 proxy can be done easy with the `-D` argument:
+
+```sh
+ssh -D 9999 ingestor.example.com
+```
+
+This can also be configured in `~/.ssh/config` so that it is automatically enabled when you connect to the ingestor:
+
+```config
+Host ingestor.example.com
+    DynamicForward 9999
+```
+
+### PuTTY (Windows)
+
+If you use PuTTY to connect to the ingestor server, add `D9999` in the Connection/SSH/Tunnels section. See the [PuTTY docs](https://the.earth.li/~sgtatham/putty/0.83/htmldoc/Chapter4.html#config-ssh-portfwd) or numerous online tutorials.
+
+## Enable it in your browser
+
+Your browser must now be configured to use the SOCKS5 proxy. This can be done several ways, but we recommend the FoxyProxy browser extension, available for [Firefox](https://addons.mozilla.org/en-US/firefox/addon/foxyproxy-standard/), [Chrome](https://chromewebstore.google.com/detail/foxyproxy/gcknhkkoolaabfmlnjonogaaifnjlfnp?pli=1), and [Edge](https://microsoftedge.microsoft.com/addons/detail/foxyproxy/flcnoalcefgkhkinjkffipfdhglnpnem?hl=en-US)
+
+After installing the add-on, add a new proxy.
+
+- *Title*: OpenEM
+- *Type*: SOCKS5
+- *Hostname*: localhost
+- *Port*: 9999
+
+After adding the proxy, make sure it is enabled (the FoxyProxy menu bar icon should be colored to match the OpenEM proxy entry).
+
+## Testing
+
+Test by going to <https://discovery.development.psi.ch>.
