I have a customer trying to setup an ipsec tunnel with me and they are not sure if their device will support it and to be honest, i'm not sure either, but I am leaning towards no. I need a better answer than my gut feeling though.
Here is the output of their show ver:
ROM: System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)
Cisco 1841 (revision 6.0) with 114688K/16384K bytes of memory.
Processor board ID FTX1104W0CS
2 FastEthernet interfaces
1 Serial interface
DRAM configuration is 64 bits wide with parity disabled.
191K bytes of NVRAM.
31488K bytes of ATA CompactFlash (Read/Write)
If this device is capable of IPSEC VPN, what do they need? OS Upgrade, addon card, its already capable, etc.
Thanks a ton! :)
