in my test environment I run BM3.8 SP4 on a NW6.5SP5 (latest Updates)
server. I configured C2S VPN as descripted in Craig's books and the
connection works fine with NMAS. After connected over VPN I'd like to ping
other servers on the LAN. Without success. Pinging is not possible, login to
NDS is not possible and also name resolution is not possible even with my
internal DNS server listed in the Client-to-Site-Konfigurations.

Any suggestions which made pinging and login enabled?
