Perhaps some kind of MTU issue ?
RDP often has MTU issues ;-)

Betreff: [pfSense Support] Is there any reason I can't Remote desktop through 
an ipsec tunnel?

I have an IPSec tunnel connecting my network to one of our customer sites, and 
while I can ping a computer on their network I am unable to remote desktop to.  
Currently all of our customer tunnels are setup to terminate in our DMZ to 
limit access back into our network.  I have a second firewall (monowall) in our 
DMZ that then routes all traffic out through the tunnel.  I've drawn a 
rudimentary layout of how it's setup (see below).

I have the IPsec rules to pass all traffic, and currently I have it setup to 
log all traffic as well.  What's strange is that when I attempt to remote 
desktop to it, I see no traffic relating to that at all.  Nothing passing, 
nothing getting blocked.  Like I said, I can ping the box just fine (and it 
shows up in the log), but I am unable to remote desktop to it and I don't see 
anything getting blocked, or passed.

Hopefully this made sense.  If it's unclear, please let me know and I'll try my 
best to clear it up.

LAN (192.168)---[pfSenseFW]---DMZ (10.100)---[monowall]---[ipsec tunnel to cust 
site]---Cust site

Thanks,

-Marty
