I'm having somes problems with the MTU size regarding the VPN Client configuration. I believe Cisco recomends changing the VPN Client MTU size to 1400. That works fine with a dial-up connection but waht if i connect my PC to a LAN? Do i have to change it to 1500 again?
Not sure what Cisco actually recommends, but I see no reason why you shouldn't have one MTU setting for your dial up adapter, and leave the Ethernet card as default.
Prior to me getting a fixed IP address on my ADSL connection at home, I used to attach the DSL direct to the USB port on my PC and run dial up networking over it - and I used to have exactly the configuration you describe. Dial up Adapter MTU was 1400 bytes, Ethernet MTU was default. It all worked fine.
