The commands are not exactly right... it should be "sudo route -n add 10.157.32.0/21 192.168.0.1" - i.e. route 10.157.32.0/255.255.248.0 to gateway 192.168.0.1. The invalid routing-table entry is
"10.157.24/21 192.168.0.1 UGSc 0 0 en1"
If you want, it is possible to schedule WebEx session on next week and look at all this directly on your machine. Let me know if you are ready to try.
Elric - Thank you so much!
I corrected the routing table entry by restarting and adding them again according to your instruction but still I can't ping any VPN-ed servers or the gateway 192.168.0.1.
I really appreciate your invitation for a webex session. I enabled email option for private messaging in my account so that you can send webex details. (Btw. I am in PST time zone, and usually available before 10:00 AM or after 7:00 PM- I have to be home to try the VPN, but I can make myself available if this window is not convenient for you)
Here is my updated routing table entries
