I am having problem with my cisco SDM. There is no response when I click Edit or Add under Firewall and ACL menu or any other menus. However I still can use wizard to create a Basic/Advanced firewall rules. I have tried different SDM version (current is 2.5) and updated my router IOS to the lastest 12.4(24)T2. My router is Cisco 871. I am using SDM because I am preparing my CCSP exam. I can still use CLI to change firewall rules with no problems... I also tried both IE 7 and Firefox and my Java is updated to the lastest as well... Any advice please? thank you!
