I have a vpn site to site configured with 2821 and 1721 routers.
Encryption is set to esp-3des esp-cha-hmac. I know that aes is better than 3des, is modern and built for this porpouse.. and faster than 3des.
Even aes(which I want to use 128) is less than 168 bit.. is stronger tan 3des?
Now, the lmds connected to stablish the vpn (4x4) is not full velocity because of the encryption, Can I use another HARD encrytion to improve the connection?
This line is about 450 KB/s to internet and to the vpn remote site 2xxKB/s
1721 has vpn module instaled
What can I do?
