## VPN bypass handling
## Configuring PAC
There are certain sites I need to connect to directly rather than through my system-wide VPN. Rather than struggling with configuring the VPN client itself to do this, I run a Linux VM in bridged networking mode. I open a dynamic forwarded port into the VM, and configure my browser to use the local port as a SOCKS proxy for the appropriate hosts.
To use an SSH tunnel as a SOCKS proxy for select domains, open a dynamic tunnel with:
### Installing Alpine Linux
These instructions should work roughly the same on VMware Player, VMware Workstation, VirtualBox, and probably others.
Create a new VM from the `alpine-virt-*.iso` image. Set its network adapter to run in bridged mode. Start the VM and sign in.
Run `setup-alpine` and go through the prompts. Most of the questions can be answered with the default answers. But when asked which disk to use, make sure you don't select `none`. And when asked what the disk should be used for, answer `sys`. Don't set a password. Reboot. Make note of the VM's local network IP address.
### Configuring `sshd`
In the VM, edit `/etc/ssh/sshd_config` and find and edit the appropriate lines to set the following config values:
```
PermitRootLogin yes
PermitEmptyPasswords yes
AllowTcpForwarding yes
```shell
$ ssh -D 8000 hostname
```
Restart the SSH server with `service sshd restart` (or restart the whole VM).
### Configuring `ssh`
On the real machine, add an entry to `~/.ssh/config` with something like:
```
Host bypass
HostName 1.2.3.4
User root
DynamicForward 8000
```
### Configuring PAC
Point the browser to use a manual proxy configuration file containing something like:
and use a manual proxy configuration file containing something like:
```js
function FindProxyForURL(url, host) {
return /(^|\.)(example\.com|example\.net)$/.test(host) ? 'SOCKS 127.0.0.1:8000' : 'DIRECT';
}
```
### Using the VPN bypass
- Start the VM
- `ssh` into the VM
