Trouble with natd and path mtu discovery (ICMP_UNREACH_NEEDFRAG)

Hi, I'm currently running into a problem using natd with a private network that does not have an overall mtu of 1500. Unfortunately the setup is quite complex and I'd like to get by without explaining it all. So for the moment I'll just ask about what I think is the problem and if you need more in
