This takes more than configuring your router. You have to configure DNS as well.
First, set up an A record for frog1.test (I assume you already have one for frog.test)
Next, you want to add an srv record to each domain record (one for frog.test, one for frog1.test).
A SRV record record contains the following information:
Service Name: the well know name of the service
Protocol: specifies if this is a TCP or UDP service
Domain Name: the domain name that this record belongs to
TTL: Time to Live value
Class: DNS class field. This always has the value of "IN"
Priority: when multiple hosts are configured for the same service, the priority determines which host is tried first
Weight: A relative weight for records with the same priority
Port: the TCP or UDP port that the service uses
Target: the name of the host providing the service
Yours will probably look like this when it's configured:
_www._tcp.frog.test. 86400 IN SRV 10 5 80 www.frog.test.
_www._tcp.frog1.test. 86400 IN SRV 10 5 443 www.frog1.test
Next we have to tell the router what to do with these connections
ip nat inside source static 10.0.0.1:80 126.96.36.199:80
ip nat inside source static 10.0.0.1:443 (IP address of frog1.test server):443
If I remember correctly, to test this on the router you type:
show ip nat translations
You should see:
frog Inside global Inside local Outside local Outside global
--- 188.8.131.52:80 10.0.0.1:80 --- ---
You should also see an entry for the 443 port.
Just to make sure we understand each other, this builds a static route from your server through the router. This won't be a DHCP set up. This means you have to set the IP address configuration in your server (gateway address, IP, subnet mask, etc).
Note: Doing all this from memory, and haven't had coffee yet
