[pptp-server] Several questions

Hi,
I'm trying to use PoPToP with the linux pptp client and I have a few questions.
First, I don't quite understand what localip and remoteip should be set to in
/etc/pptpd.conf
I'm running PoPToP on a double nic'd box. The external interface is
207.207.30.130. The nic on the inside is 10.10.10.1. I've designated the range
10.10.10.150-199 as usable for our VPN.
So, right now my /etc/pptp.conf file looks like:
speed 115200
localip 207.207.30.130
remoteip 10.10.10.150-199
Is that correct?
Next question. The box PoPToP is running on is doing masq/nat so our internal
network is walled off. I've read several messages in the mailing list about
PoPToP and firewalls and forewarding but I'm not sure if it applies in my
situation. Does it? And, if so, what do I need to do?
Finally, despite all of the above, I think I'm getting a successful PPP
connection with PoPToP as shown below:
$ sudo pptp 207.207.30.130 debug name jbodnar
(unknown)[9194]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]: Client
connection established.
(unknown)[9194]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing call
established.
If I do an ifconfig I have a ppp interface present on the client:
[jbodnar at mrmagoo jbodnar]$ ifconfig
ppp0 Link encap:Point-to-Point Protocol
inet addr:10.10.10.151 P-t-P:207.207.30.130 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:9 errors:0 dropped:0 overruns:0 frame:0
TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
and the server:
[jbodnar at mail jbodnar]$ /sbin/ifconfig
ppp0 Link encap:Point-to-Point Protocol
inet addr:207.207.30.130 P-t-P:10.10.10.151 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:8 errors:0 dropped:0 overruns:0 frame:0
TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
Now, back on the client I tried:
$ sudo route add -net 10.10.10.0 netmask 255.255.255.0 gw 207.207.30.130
but even after that I can't ping anything on the 10.10.10.0 network.
Is this due to possible mistakes with setting up pptp or firewalling? Or am I
doing something wrong with routing on the client side?
Thank you.

I couldn't very well chop your hand off and bring it to the store,
could I?
