TunnelCat VPN vs. other VPN
1. Fully Configurable VPN
2. Has different tunneling methods
3. Much stable
4. Voluntary Servers

6. User Friendly
7. Import Payload
8. Official servers are load balanced
9. Powered by OpenVPN
10. Free

Direct Method -> OpenVPN:
The direct method only uses the OpenVPN protocol and does not use any tunnelling method such as HTTP, DNS or SSL

DNS Tunneling Method -> OpenVPN over DNS:
Note that the DNS method uses a very slow tunnelling method. The payload setting can be set into a custom DNS IP with this format:

DNS payload format:
SSL Tunneling Method -> OpenVPN over SSL:
If you chose the SSL tunnelling method you can set the SNI through the payload setting with this format:
SSL payload format:
HTTP Tunneling Method -> OpenVPN over HTTP:
The HTTP tunnelling method payload setting uses the same syntax as HTTP Injector. You can generate through it then use it for this app
HTTP Syntax Format:
for manual payload setting syntax you can visit the documentation of the app here:
You must register or login to view this.
Payload Setting for HTTP example:
CONNECT [host_port] [protocol][crlf][crlf]
Repository URL:
The repository contains server list and configuration that application can use, you can create your own repo once the API for the voluntary server is online.

Importing .tcat (TunnelCat Payload Configuration):
.tcat files contain payload preset which is locked by default

Important Notes:
Once the Payload Settings is detected empty the default direct method will be used

Online TunnelCat Payload Generator (this generates .tcat file):

Ugaliing mag-basa nang mga nasa baba ^_^

Bakit mabagal?
If you are using the DNS tunneling method the connection will be around 1mbit up/dl and wala na po akong magagawa para mas mapabilis yan. Change nalang tayo into faster method like SSL or HTTP

Bakit no browse?
This problem occurs when you are using the DNS tunneling method, this issue depends on your phone's Operating System not the app it self. The fix is to use other Operating System or use another tunneling method.

Bakit kokonti lang servers?
You can donate if you want na magdadagdagan.

What type of donation do you accept?
Cash or server if you want to.

Bakit may ads?
Pang add sa the mga maintenance of the VPN servers.
If you don't want to see ads you can use an ad-blocker. Simple as that.
