Change mtu client from dhcp server


My DHCP server runs on Debian and serves IP's only to the local network. The server is a NAT router as well and thus I need to set the MTU on the client interfaces to 1452. Otherwise some webpages will be unavailable due to packet fragmentation.

I can set the MTU on the clients in /etc/network/interfaces with the 'pre-up' option, but would like to let the server handle this and let it tell the clients to use a different MTU. I thought 'option interface-mtu' in the dhcpd.conf file could do this, but it doesn't do a thing. How do I solve this?

Could it be that 'option interface-mtu' only applies to the interface serving the dhcp leases? Where are the experts? ;-)

Did you ever find an answer to this question? I'm using Centos 4.8 and observe the same thing.
