Thanks Jordan, appreciated. I can see that solution will work for configs for packets without the IPsec header, but ours do, which further lowers the max MTU to 1432. It sounds like there is not necessarily going to be a customisable MTU, but the new value will instead be fixed at 1460?
I can add a comment to the Issue Tracker if it's appropriate, so that the engineering team takes the VPN case into account when implementing a fix.
