[Openswan Users] MTU issues with Openswan tunnel

I have several ipsec tunnels to various clients and recently added a new one for a new client. With this new client's VPN connection, nothing (ie FTP, terminal sevices, etc) seems to work well unless I manually set the MTU value for Openswan to 1400. However setting the MTU to 1400 screws up my other ipsec tunnels. Is there a way to set the MTU value for just one tunnel?
The symptoms are very strange. If I leave the MTU value at the default, I can get one or two terminal sessions via the new tunnel but any additional attempts time out. If I change it to 1400 the new tunnel works great but my other established tunnels only allow one or two connections. I have tried values between 1400 and 1500 but have been unable to find any middle ground that works well.
Thanks for your help.
