forgive me if I am having a bonehead moment.
for years I have had no problem using the windows client to connect to several clients sites with simple PPTP to their Mikrotik. however recently Comcast has forced me to use their xfi gateway instead of my own modem. the xfi gateway is in bridge mode and everything seems great but if I try to connect to a MikroTik with PPTP i see the connection made in the log but then nothing. it all hangs.
If i take my MikroTik out of the way and connect directly to the xfi gateway it works.
it also works if I set up a client on the Mikrotik itself
so:
computer–>Mikrotik–>Surboard modem–>PPTP works
computer–>Mikrotik–>xfi gateway–>PPTP fails
Mikrotik–>xfi gateway–>PPTP works
i have fully reet the Mikrotik (ccr1009) with the simplest setup I could
DHCP Client (to grab public from comcast)
DHCP Server (to server my local lan)
local IP on my eth2 for dhcp local netwok
1 nat rule src–local subnet–masqerade
what am I missing?
