[pptp-server] New setup help... NAT on FLowPoint router

[Allen Moore]

I have successfully configured pptpd to function within my small lan;
however, calls from the outside via the internet go unanswered.  I fear
that my FlowPoint DSL router may be the culprit.

I have NAT enabled & calls to WEB, TELNET & FTP services properly
forwarded to my server and have added a NAT entry for TCP port 1723;
however when I try to add protocol 47 (GRE) I get a 'bad protocol'
message from my router.

Anyone here have any FlowPoint experience?  Is my suspicion correct that
I must replace the router?  What is an inexpensive DSL router known to
work w/ PoPToP?  For remote access via the internet, I assume that the
pptpd.conf file still uses the servers own ip as the localip, even
though from the outside we login to the gateway (external) ip on the
router, or am I missing something here, too?

TIA for any help!
