That is my first time posting right here – hope I am asking within the acceptable place 🙂
I’m coaching now with pc networking ideas, and one factor that I used to be interested in is configuring VPN tunnel by means of the web utilizing Dynamic DNS on each ends. I want to see if anybody will be capable of assist me with this process.
I am utilizing GNS3 and Cisco router GNS3 home equipment.
I’ve discovered the way in which to configure IPsec with DDNS on a Cisco’s IOS CLI, however one of many circumstances is to attach the outbound interface to the ISP.
In my home scenario, I take advantage of a client router (Asus CM-32 AC2600) which is related to my ISP.
I used the Cloud equipment on GNS3 and I managed to attach my digital GNS3 router to the web through the cloud, enabling “IP deal with DHCP” on the Cisco’s interface – it will get an IP from my Asus (main home router) as every other LAN system, and it has entry to the web.
I created an account on http://freedns.afraid.org/ and created a subdomain to make use of for my Cisco router.
I attempted to configure DDNS on the Cisco router in accordance with some directions I’ve discovered:

R1(config)#ip ddns replace methodology Method_name
R1(DDNS-update-method)#http
R1(DDNS-HTTP)#add http://person:password@freedns.afraid.org/nic/replace?hostname=<h>&myip=<a>
R1(DDNS-HTTP)#exit
R1(DDNS-update-method)#interval minimal 0 12 Zero 0
R1(DDNS-update-method)#exit
R1(config)#int e0/0
R1(config-if)#ip ddns replace DNS_SERVICE_NAME
R1(config-if)#ip ddns replace hostname subdomain.area.com
R1(config-if)#ip deal with dhcp
R1(config-if)#no shutdown
R1(config-if)#do debug ip ddns replace

After which I’ve acquired these messages:

*Mar  1 02:46:43.310: DYNUPD: SWIF comingup 'Ethernet0/0'
*Mar  1 02:46:43.318: DYNUPD: SWIF comingup 'Ethernet0/0'

Will probably be actually nice if anybody may share with me a course for an answer

• I have to point out that my first purpose is to map an FQDN to my Cisco router, the above config is just not together with any IPsec/ VPN issues, solely Dynamic DNS.

Cheers!
