+## Multiple networks with non-default gateways
+
+In some multiple network configurations it may be necessary to manage default
+routes rather than them being automatically created from a subnet gateway.
+This can be done using the tofu variable `gateway_ip` which can be set for the
+cluster and/or overriden on the compute and login groups. If this is set:
+- a default route via that address will be created on the appropriate interface
+  during boot if it does not exist
+- any other default routes will be removed
+
+For example the cluster configuration below has a "campus" network with a
+default gateway which provides inbound SSH / ondemand access and outbound
+internet  attached only to the login nodes, and a "data" network attached to
+all nodes. The "data" network has no gateway IP set on its subnet to avoid dual
+default routes and routing conflicts on the multi-homed login nodes, but does
+have outbound connectivity via a router:
+
+```terraform
+cluster_networks = [
+  {
+    network = "data" # access network, CIDR 172.16.0.0/23
+    subnet = "data_subnet"
+  }
+]
+
+login = {
+  interactive = {
+    nodes = ["login-0"]
+    extra_networks = [
+      {
+        network = "campus"
+        subnet = "campus_subnet"
+      }
+    ]
+  }
+}
+compute = {
+  general = {
+    nodes = ["compute-0", "compute-1"]
+  }
+  gateway_ip =  "172.16.0.1" # Router interface
+}
+```
+
+If there is no default route at all (either from a subnet gateway or from
+`gateway_ip`) then a dummy route is created via the access network interface to
+ensure [correct](https://docs.k3s.io/installation/airgap#default-network-route)
+`k3s` operation.
+
+When using a subnet with no default gateway, OpenStack's nameserver for the
+subnet may refuse lookups. External nameservers can be defined using the
+[resolv_conf](../ansible/roles/resolv_conf/README.md) role.
+
+## Proxies
+
+If some nodes have no outbound connectivity via any networks, the cluster can
+be configured to deploy a [squid proxy](https://www.squid-cache.org/) on a node
+with outbound connectivity. Assuming the `compute` and `control` nodes have no
+outbound connectivity and the `login` node does, the minimal configuration for
+this is:
+
+```yaml
+# environments/$SITE/inventory/groups:
+[squid:children]
+login
+[proxy:children]
+control
+compute
+```
+
+```yaml
+# environments/$SITE/inventory/group_vars/all/squid.yml:
+# these are just examples
+squid_cache_disk: 1024 # MB
+squid_cache_mem: '12 GB'
+```
+
+Note that name resolution must still be possible and may require defining an
+nameserver which is directly reachable from the node using the
+[resolv_conf](../ansible/roles/resolv_conf/README.md)
+role.
