Troubleshooting PPTP VPN passthrough on Fios router MI424WR

I have configured a PPTP VPN server to my Synology DiskStation at home network. All the clients on the home network can access the VPN server just fine while any client on the Internet is not.

I've setup the port forwarding rules for PPTP on the Fios router MI424WR Gen-2 (1723 TCP + GRE) but no avail. The Internet clients clearly see the VPN server on my home network, but they are not able to establish the data connection (hangs on "opening the connection" or "verifying the username/password" depending on the client). Without the port forwarding rules VPN clients just hangs out "no server available".

I've also double checked the Synology own firewall settings are correct.

I'm guessing the Fios router does not support the GRE implementation by Synology.

Any help would be highly appreciated.

They do GRE if you use the preconfigured port forward rules.

Try to delete your PF rule, and use the Built in PF instead.

Yes, I used the Fios router built-in PPTP port forwarding rule to enable 1723 TCP and GRE. No success.

I am having the same issue. I am thinking this may be a firmware problem.

double check with actiontec, I set up a vpn just this week for a friend that had the newer actiontec (two antennas verizon firmware), only needed three ports open and everything worked flawlessly within minutes going to an apple server. He did the apple server side, and I helped him do the actiontec. His problem was he kept going into advanced settings instead of just sticking with the basic port forward. iow he was making it harder for himself than he needed to.

I followed these instructions here.

I have tryed everything to get this to work. I may need to go back to comcast. I contaced both support lines (verizon and the modem). I am out of options. Anyone else get this to work?

definetely not a firmware problem, a lot of users do vpn's, you have to roll up your sleeves and dig in. it's probably something small your missing, OR you are too focused on the router.

the router is 5 seconds of configuring, and THAT'S IT. don't spend any more than that looking at the router GUI.

Your rule should be simple

your ip 192.168.1.x

source port is always ANY

destination port addess xxxxx

protocol (pick your poison) tcp or udp.

For the latest vpn the vendor wanted one udp and 3 tcp ports forwarded.

after that go back to your pc (windows firewall, norton, mcafee etc...) or VPN software and configure it properly.

Same problem here, I just got FIOS this week, I had comcast before with a CISCO 3500 wireless router. NOTHING changed on my internal serve and internally VPN connecction works, it's something with the FIOS router. I found another bug also, with FTP. If Im working from home, and VPN to work.. then while VPN's to work I try to FTP to my server the router gets confused thinks I should be external when I'm internal. The Cisco/linksys router worked fine, but fios router doesn't and I have the new rev I router.

Quite a few people have gotten it to work.

Two things that I don't think were mentioned that stand out when looking at these, is Make sure your Device IP Address is NOT in the .100 range. The Set top boxes for TV use the .100 range, and also, some users couldn't get it to work over Coax, and had to run ethernet cords from the ONT to their router, and then call verizon to switch it, and that seemed to work for some people.

It took a bit, but it does work. Heres what I did.

Step 1 : Have verizon tech support swap you from coax to ethernet on the ONT

Step 2 : Connct both coax and ethernet to your Actiontec router

Step 3 : Use the firewall to port forward both IPSEC as well as PPTP to your dedicated vpn server

I have a belkin sharemax n300 running tomato USB acting as my torrent server, web server ( lighttpd ) , ssh tunnel server, ftp server, SMB server, and pptp vpn server. It was a pain but everything does work. The belkin is hosting everything through optware and the built in tomato services. Im conected as follows :

------ Cat 5 WAN -----------------> Actiontec Verizon router ------> Belkin N300 Server

-------Coax ( F pin cable line ) ---- --------^

I have all tv guides working along with my server services. It takes a bit to configure everything on the actiontec, but its worth the wait. Every service has to be forwarded that you want to use ...UGH. I tried PPTP alone but it wasnt working. Once I added IPSEC to the actiontec forwarding to the belkin, everything began working seamlessly. Im using the built in PPTP server that comes with TomatoUSB. It wasnt worth the hassle of creating openVPN keys for me. This is just a home setup.

I hope this helps !!!
