Posted on 2013-11-20

Please can anyone give me some direction over replacing a juniper router with a cisco 2901.
I am having issues with a cloud partner router and want to bypass this with a cisco.

I need some advise on how to set up ipsec tunnel to the provider and static routes to point there for hosts desktops.  also will this affect NATing of protocols for my voice and data ?

the vpn detail are :

VPN Details
VPN Name
Hosted End-Point IP
On-premise End-Point IP Address
On-Premise Network
On-Premise Subnet Mask
Pre-Shared Key
IKE Phase 1
Pre-Share Diffie-Hellman Group 2
86400s (1 day)
IKE Phase 2
3600s (1 hour)

any help would be muchly appreciated. Thank you for your time

Well, that's all the info you need to configure the VPN, so you should be good.  Are you looking for the exact commands to enter?

Hello and thank you for repsonding

yes and also knowing where to create this .....

is it on the sub interface of the data vlan as its for users to connect to a hosted desktop provider and do not need the voice vlan to utilise this route etc

i hope i make sense , its just the  leasedline supplier will not give us a wires only service and we are having issues with their router esp for voip....  sorry for going on
