[edgar-quintana]

Hi,

This is my problem:

-Ive a lmds 4 simetric connection attached to my cisco 1721 with wic 1enet. Downloading from internet and uploading to internet work properly uo tu 450 KB/s, but using a vpn 3des the upload is only up to 50 or 60 KB

Why?

Best regards

This is my hard

Cisco 1721 (MPC860P) processor (revision 0x300) with 114688K/16384K bytes of memory.

Processor board ID FOC07470APD (213828379), with hardware revision 0000

MPC860P processor: part number 5, mask 2

1 Ethernet interface

1 FastEthernet interface

1 ATM interface

1 Virtual Private Network (VPN) Module

32K bytes of NVRAM.

32768K bytes of processor board System flash (Read/Write)

With this hard, and this soft

System returned to ROM by power-on

System restarted at 15:26:04 Romania Mon Jun 4 2007

System image file is "flash:c1700-k9o3sy7-mz.124-5.BIN"

Can I upgrade to the mentioned IOS version??

Hi,

You have 12.4.5 image and the first release where this bug fixed is 12.4.5a so you have to upgrade to that at least (or later image listed earlier).

Hope it helps,

Then.. the solution is upgrade IOS version ok? but is possible to upgrade? Have I enough memory?

[edgar-quintana]

Will these versions work?

c1700-k9o3sy7-mz.124-11 T.bin

c1700-adventerprisek9 -mz 124-8.bin

are valid ios versions?

Hi,

Now my cisco 1721 has vpn module and full of memory... then there is a doubt

Which will be the top of uploading(using 3des encryption)velocity possible if there is a 4 simetric connection...the other vpn side is a cisco router biger than a 1721.. such as 2800 or like this.

Velocity aprox...

Hi,

As earlier wrote "With VPN module you will be able to encrypt at E1 speed (2Mbps) and establish roughly 100 ipsec tunnels". The ISR routers (850, 870, 1800, 2800, 3800 series) are different things in respect to the IPS/SSL performance since they have totally different hardware architecture. For instance the 870 series maximum 3DES throughput is 30Mbps. I'm afraid you won't be able to take advantage of the 4Mbps line unless you upgrading to new, stronger platform.

Hi,

Then, which device would you choose?
