I've trying to configure site to site VPN between Site1 and site2 using Cisco 871 on both sites
Site 1 is Cisco 871 where Dialer0 is External Interface and site2 is also Cisco871 where FastEthernet4 as external interface.
Site 2 has static IP and site 1 has PPPoE (Static)
I went through all the configuration steps and tunnel debugging made tunnel up now.
I can ping the servers from both sites using IP address but I can't ping with hostname. But I can access data using \\192.168.xx.xx on either sites.
Site 1 has two servers, one DC and the other Mail.
Site 2 has a File server joined to the domain. And I am going to make this secondary DC after the site to site vpn is sorted. If hostname doesn't resolve, then I can't promote this server into sec DC. Am I right?
I think there is something to do with NATing, could anyone help me out.
I have attached the IPsec & NATing portion of my config as below:
