[Sonugnair_2]

Hi,

I am having a 1841 router that has IOS "C1841-IPBASE-M" (flash:c1841-ipbase-mz.124-1c.bin). Now i need to set up IPSec VPN on this router. SO which IOS should be choosen for this?

a) c1841-advsecurityk9-mz - ADVANCED SECURITY

b) c1841-advipservicesk9-mz ADVANCED IP SERVICES

The hardware specs are:-

DRAM configuration is 64 bits wide with parity disabled.

191K bytes of NVRAM.

31360K bytes of ATA CompactFlash (Read/Write)

Thanks and Regards

Sonu

Hi Sonu

Advanced Security contains the required IOS Firewall/IPSEC/DES/3DES/VPN Functionality...

Advanced IP Services contains Advanced Security set features as well as Service Provider Services features...

You can decide on which ios feature set and ios code name using feature navigator tool and software advisor tool...
