VPN site-to-site IPSec tunnel

Hi!

I try to setup VPN IPsec tunnel on two MT v6.22. I have established connection, but I cannot ping from side to side. I have NAT rule done as a first. I do not see any traffic on both sides. Can somebody post how to troubleshoot this problem, please ?

I can do a Join.me session with you tomorrow night around 9pm Mountain Time if you want. Should be able to get it figured out pretty quick. Email me at mike(at)43index.com if you want to set something up.

Good Morning guys,

Relevant to your discussion I’m having issues with my PPTP connection, do you recommend IpSec tunnelling for LAN to LAN vpn??

Hi!
Do you have setup cilent-to-server by PPTP ?

Yes and every 20 minutes i get a dropdown and a redial after 2 minutes!!!

Try to go on-site and setup login to MT and at the same time setup some remote session to computer where you use VPN PPTP connection. Then ping from remote on WAN and Local interface. When connection will be dropped you will see where is problem, on Mt or in the network.

Check also session timeout in VPN profiles.

I would always use IPSEC over PPTP as it is more secure…

Same thing with the IpSEC

Can IPsec be applied between two sites over the internet with dynamic ip on both sides?

Sure it can but if your address changes you will have to update the tunnel config on both sides with the new IP. This is where services like no-ip.com come in really handy, then you don’t have to update the routers. Just go to the website and update the DNS.

Can you tell me how I put in the dynamic address (eg xxx.dyndns.org) into the VPN setup rather than the IP address?

Thanks

You need the ddns updater script
