I think 32mb CF memory is not enough. At least 64 mb would be sufficient.

Do you have an encryption card?

Ok. What IPSec VPN do you have in mind? DMVPN? IPSec over GRE? IPSec using Virtual Tunnel Interface?

Feature set you need to be looking for is AT LEAST Advance Security and this would require up to 24 Mb. Advance IP would make it above 32 Mb.

Please note that if you do not have any hardware encryption card on board you'll be using the router's CPU to encryp/decrypt. Please be aware that this could slow down the throughput of the 1841 router.
