Need some advice,
I have a cbeyond SIP phone service, works great. After discussion with cbeyond technician and my Cisco Systems Engineer, it was suggested that I alter my Fastethernet0/0 IP address to a Global IP address, for obvious reasons.
I used CCA2.0.1 to alter my internet IP address.
I can still browse to the internet, but my UC520 is now using a Global IP address given to me by cbeyond rather than the private IP address that it was using before.
I next added a NAT entry to allow for a port Address translation from my wan interface to my lan interface port 5722 to private IP 192.168.10.200
My concern is that my acess list now looks too brief, and look too restrictive
here is the OLD access list;
access-list 105 remark auto generated by SDM firewall configuration##NO_ACES_20##
access-list 105 remark SDM_ACL Category=1

here is my show run of my FastEthernet0/0 interface and new access list that is attached to FastEthernet0/0

My concern is regarding the old access list 105 took into account allowing SIP from my service provider and other necessary services. The new access list does not take into account these DNS, SIP and ICMP services.
How can I use CCA2.0.1 to allow the SIP connection from CBeyond , Domain services and ICMP functionality.
