And now the UDP scan, but only against those ports, plus one port that I know to be closed (that's a sanity check) :sudo nmap -sU -T5 -p 500,1701,4500,9999 xx.xx.xx.xx Starting http://forumyaren.com/vpn-error/vpn-error-806-comcast.php
Problem is NOTHING is seenback from 174.x.x.x to complete that request to start the connect from 18.104.22.168, which alsocorrelates what you told me earlier, namelysaid by stevemayman:Telnet connection failed on 1723. I tried many thing but couldn't get it to work. It seems like comcast has had this issue before. 0 Kudos Posted by EG 10-15-2011 04:46 PM Connection Expert View All Member Since: 12-24-2003 Posts: 52,506 Message 12 of 18 (6,729 Dashboard for XFINITY TV on the X1 Platform Get details on weather, traffic, sports and more all from your XFINITY TV on the X1 Platform Dashboard. http://forums.xfinity.com/t5/Your-Home-Network/VPN-stopped-working/td-p/1070869

Also, you should ping your VPN server to see if it is reachable. It could be a problem with the provider but I doubt it. Home network administrators normally perform these changes on a broadband router. news I'll also run the simultaneous capture from the office as you suggest, but the logistics of it mean that it won't be until next week.
I am a paying customer just like you! They claim they are not, as the modem is in a bridge mode and does no authentications (it leaves it up all to the router to do that).I'm running out of You're probably wondering, HEY, WHAT ABOUT THE LOG ON YOUR SERVER ADMIN PAGE?I've been looking at the log, and there's a whole lot of nothing.
I am a paying customer just like you! It's not the same as configuring your firewall to permit inbound traffic on VPN ports. I've looked at both of the things you mentioned and unfortunately I'm still hitting a roadblock.I have since replaced the D-Link with the router we were using originally. I disabled the modem firewall, computer firewall, antivirus, etc but it still fails.Can anyone suggest some solutions on it.Error: 619, Connection cannot be established... 0 Kudos All Forum Topics Previous Topic

Odd thing is I can still log in fine from the same laptop if I use my neighbor's WIFI instead of my own.Must be something on my home router/gateway right? I don't remember what the problem was, but our IT department worked with Comcast to resolve it. Exactly what I needed.I can't ping the DYNDNS server on the failing connection.

Neverheard this one off the top of my head, but ANY sort of specific error message is ALWAYS helpful for troubleshooting.Can't tell you where'd Windows would keep the VPN logs, you I can try that and see if that works. That clearly indicates that you have VPN set up properly inside. plus the error tells me potentially at a layer 3 or layer 4 level, traffic is not making it tosaid VPN server from the nonworking connection.
