I have a 877 ISR router that has been running 12.4(15)T7 for a while without problems. Recently I experimented with the SSL VPN features through SDM and realised I needed more memory (FLASH & DRAM). I have now upgraded the FLASH & DRAM to the maximum it can take (52MB FLASH & 256MB DRAM). I have also upgraded the IOS to the very latest 12.4(22)T but some features of SDM have stopped working.
When SDM is started it connects to the router and starts parsing the configuration. During this it stops and a dialogue box appears stating 'SDM cannot connect to your router for the following reason: communication exception' If I click OK SDM continues to load and another dialogue box appears: 'In order for SDM to deliver commands to your router, SDM needs to write a temporary file to your router's flash'. I then click OK and SDM is running and the Home page shows everything except NAC is configured (which is correct). If I click the configure button, then click 'IPS' I get a page saying HTTP or HTTPS needs to be enabled and that HTTPS has been detected, however the pages that were previously available are not there. If I look at the SSL VPN configuration pages it tells me that the SSL VPN Client software is not installed, however from the CLI it is shown as installed.
I have made no changes to the configuration between the IOS & memory upgrade but there was some playing around due to the FLASH upgrade, however I am pretty certain it is back to how it was previously.
I am running the latest version of SDM (2.5).
