No, it doesnt matter.
Which interface are you using to connect to Internet? Replace it with the dialer1
>> ip nat inside source static tcp 10.0.10.30 2101 Dialer1 2101
Any request that comes in your external interface <here Dialer1> port 2101 will be forwarded to the port 2101 of the internal IP 10.0.10.30.
