## Ports and addresses Pachca needs to work properly: setting up your corporate firewall

Before your company starts using Pachca, you need to add a few addresses and ports to your allowlist. This keeps Pachca working properly while you test and roll it out.

The email addresses are used for signing up and logging in to Pachca, and the ports are needed for all Pachca features to work.

### **Email addresses for signing up and logging in to Pachca**

- [greg@pachca.com](mailto:greg@pachca.com)
- [no-reply@go.pachca.com](mailto:no-reply@go.pachca.com)

If your email service blocks these addresses, users won't get their verification codes and won't be able to log in to Pachca.

### **Ports Pachca needs**

Ports for the app:

- 80/tcp 443/tcp

Ports for video calls:

- 3478/udp 5349/tcp 10000-20000/udp
- TCP/UDP 7881
- UDP 49000–60000
- TCP 5350, TCP/UDP 3478, TCP/UDP 3479
- TCP 443

If these ports are blocked, chats and calls won't work.

### **IP addresses Pachca needs**

- 37.200.70.176
- 91.105.198.129
- 31.184.217.131

IP addresses for video calls:

- 212.41.8.70
- 178.130.58.130
- 45.159.209.107

### **IP addresses we send webhooks from**

- 37.200.70.177
- 185.209.115.174
- 135.106.159.61

If your company uses a private subnet, add these addresses to set up network access to app.pachca.com.
