i am having a head-ache to build up a configuration.this is what i need:
i have a Head Office server running SBS 200 + a Point of sale System (xbased). i also have to remote shops that use the same POS system. but the system is not live. i am trying to build up a live system. for that purpose i am setting up adsl connections at the three locations.( i only have this possibility)
Head Office : 512kbps ADSL with Fixed IP address 213.x.x.200 LAN ip address of server is 22.214.171.124
I don't think there is a way to forward all GRE packets from the IOS device to the win2k server.
I would recommend putting a 10 user pix 501 firewall in each remote office for US$400ish apiece, and setting up IPSec tunnels from them to the IOS device - this will separate your network layer from the windows networking layer and will help troubleshooting, IMHO
