This table is a generalisation to show the strongest advantages of Dull. We welcome feedback and criticism to improve the accuracy of this comparison table. For corrections, please email [email protected]

Full site-to-site private inter networking

Dull doesn't currently include a Virtual Network Adaptor header. Such a header allows multiplexing of Layer 2 network traffic on a LAN, and thereby bridging two remote LANs. This kind of function is best implemented with a traditional VPN system, this is not the purpose of Dull. Dull could be used as the tunnelling framework to base such a site-to-site VPN system on. In fact, a Layer 3 implementation with routing could use a variety of Dull tunnels to comply with various rules. But for now, there is no native Virtual Network Adaptor support, nor multiplexing support.

Remote Access software

This columns is included and covers a very broad range of remote access software. If we expanded this it would be quite tedious to compare. We are thinking of very popular remote access software for this column, but also some lesser known. We have combined the features across a range of tools we know. A separate table just for comparing with remote access software would be the best approach in the future to be accurate, fair, and invite those vendors to correct any inaccuracies they might find.

OpenVPN column

This column was specifically included because it's very good and popular VPN software. As you can see in the table it accomplishes much more than what other traditional VPN systems can. We suggest that OpenVPN and MPLS are better choices enterprise internal multisite virtual private networking. For the purposes of support, that goes beyond a single organisation, Dull is more focused and accomplishes much more for such scenarios.


Refers to PPTP, L2TP and IPSec. It doesn't refer to private web browsing services.

SSH / Wireguard

These are very useful and important tools. In fact, we expect to include such tunnelling protocols in the future as duct types, particularly Wireguard. These protocols are typically used for administration of servers by system administrators. These protocols are usually implemented in a way that a client connection results in a command-line terminal user interface, but port tunnelling is also possible.
