Walter,

Thanks a million for taking the time to check my 'config'.

Are you suggesting that my config should look like this (below)? Can
you predict whether I'll destroy the VPN (which is in use by 10
employees) by loading the suggested config? (I'm not asking you to take
on any liability, just wondering what to prepare for if it does explode
on me)...guess I could back it up first. Here's your copied suggestion:

"""Yup. It's messed up.

name 192.168.4.192 WEB
object-group service HTTPHTTPS tcp
  port-object eq www
  port-object eq https

access-list outside_access_in permit tcp any interface outside
object-group HTTPHTTPS
static (inside,outside) tcp interface www WEB www netmask
255.255.255.255 0 0
static (inside,outside) tcp interface https WEB https netmask
255.255.255.255 0 0

access-list outside_cryptomap_nonat permit ip any 192.168.255.80
255.255.255.240
access-list outside_cryptomap_dyn_20 permit ip any 192.168.255.80
255.255.255.240

nat (inside) 0 access-list outside_cryptomap_nonat

ip local pool VPNIP 192.168.255.80-192.168.255.95

crypto dynamic-map outside_dyn_map 20 match-address
outside_cryptomap_dyn_20
crypto map outside_map 65535 ipsec-isakmp dynamic outside_dyn_map
crypto map outside_map 65535 set transform-set ESP-3DES-MD5

vpngroup rcmsremote address-pool VPNIP
""""

Thanks again! I really appreciate the help on this one.
