The following works in my configuration of Verizon DSL using PPPOE. Before I found the correct settings below the SecureClient would report Packet Fragmentation Errors.

1. Make sure you are using the latest SecureClient build from Checkpoint.
2. In the SecureClient software choose: Tools > Advanced IKE Settings. Select both "Force UDP Encapsulation" and "Support IKE over TCP"
3. Make sure that the SMC Router MTU is set to 1492. To change router MTU go to "192.168.123.254/sysp.htm"
4. Change your PC MTU to 1000 using DrTCP. You can get the lateest DrTCP from "http://www.dslreports.com/front/drtcp.html"
5. Reboot PC
6. Log in and enjoy...

Using this configuration I lost about 4% of my D/L speed due to the reduced MTU.
