Nat configuration in cisco router pdf
Improve company productivity with a Business Account. I am planning to buy 2 Cisco ASA5505 devices so that I can setup a site to site VPN between 2 branches. In each branch there is currently nat configuration in cisco router pdf ADSL router that provides internet to internal users.
The DSL routers are running NAT. Will the ipsec site to site vpn work through these DSL routers ? Do I go ahead with the purchase ? Really depends on the 2 dsl routers that you have. Other option you’d have is to turn bridging mode on on the dsl routers and let the firewalls handle the routing.
If you could provide more information about the dsl routers make and model I could give you a more specific answer. You need to put the DSL routers in bridged mode and assign the public IP directly to the ASA start doing your NAT on the ASA. Also in order for the site to site VPN to work correctly you need to have static IPs from your ISP. The ASA 5505 at each site for site-to-site vpn is a workable solution, you just need to get the public IP on the ASA interface.
If ip put the public ip on the ASA5505 interface, will I still need to bridge the DSL routers ? What Kind of Coding Program is Right for You? There are many ways to learn to code these days. From coding bootcamps like Flatiron School to online courses to totally free beginner resources.
The best way to learn to code depends on many factors, but the most important one is you. See what course is best for you. If ip put the static public ip on the ASA5505 interface, will I still need to bridge the DSL routers ? Darkag, you said “you just need to get the public IP on the ASA interface. ADSL modems support NAT traversal or vpn passthrough ? I’m not sure but maybe this person has had a similar problem ? If you have the speedstream in bridge mode and therefore the ASA with the public address you don’t have to worry about NAT traversal or vpn passthrough, as the dsl router effectively becomes a media convertor.
I saw the option on the speedstream modem to change to Bridge mode. However when I click “bridge” there are no options to set and the DSL loses connection to the internet. How is the bridge to be configured ? You need the other devices in place when you convert to Bridge mode. I should be able to get static ip’s for the sites. If I cannot get the bridge to work what are my options ? Does this mean the ASA vpn will not work in my scenario ?
