Hello! I am from Hong Kong (sorry for my English ). I signed up for the PCCW FTTH service earlier this month but I found out that the modem they provided is a Huawei HG8045 GPON terminal which is a modem router combo.
The problem is that my ISP wont provide admin access to HG8045's web administration interface, I can only tinker some minor settings e.g. port forward, DMZ, wifi ssid, wifi security..etc, using an "user" account which I obviously cant disable NAT and change that to a bridge nor enabling PPTP passthough.
The old Linksys RV042 comes handy to bypass internet block at workplace or public wifi AP with PPTP server VPN function but I it barely works behind NAT, I can never connect to the pptp server at work, I tried forwarding port 1723 but it doesnt help.
I googled a bit and found that pptp uses GRE encapsulation which is not bound to a port and my only last hope is to assign my RV042's IP to DMZ, though it sort of worked as I can establish a VPN connection, got a valid ip from the RV042 and the RV042 administration interface could be accessed, strange that I cant visit any other webpages through PPTP tunnel.
Before troubleshooting other possible problems i.e. DNS setting, I would like to know if DMZ is a viable solution to pptp server behind NAT? Does it solves the GRE problem?
I swear to god, I will hack this router's admin account, they seems to left HG8045's telnet opened and telnet root account at default, I can even enter a linux shell mode though telnet , but that's another story I will probably open another thread for that.
