SBS 2003 R2 - pptp to SBS but can't ping to LAN clients
Posted on 2007-08-11
Ive done this thirty times if Ive done it once, but I cant figure it out. Im sure you guys know&
New SBS 2003 R2 (standard). No ISA. Single nic install. Sonicwall TZ180 passing PPTP to the SBS. SBS is the DNS for the site. There is no other routers involved. All CEICW wizards have been run. Its setup absolutely like I would expect it to be.
From the outside, I can create a PPTP tunnel to the sbs and ping/vnc/do whatever to it as though I were local.
I cant ping/vnc/do anything to any other IP on the SBS LAN.
Windows firewall on the clients are controlled by GPO and allow ICMP and VNC (standard build for my SBS boxes&setup just like other sites where this issue doesnt exist).
Trend 3.6 is the AV.
Attempting to ping does resolve the IP of the inside machines on the SBS lan, but I cant get a response from them.
On the SonicWall, other than my WAN>LAN rules for the basics (smtp, pptp, ssl, rww), the default LAN>WAN rules are present. (thinking outbound routing from the SBS LAN might be the culprit, but&)
Any ideas? What could keep me from VNC/ping to the LAN clients? Trend
