Hi There,
I was working 10 years ago as network engineer where i used many Cisco products, i finally completly changed of job
But 10 years later, i'm launching a new project where i really need my old network competences... The problem is that i don't remember anything about what i learnt 10 years ago I'm right now taking a look to my old CCNI books to find out how to set Eth interfaces in IOS !! i'm really not proud
I've found out an old 1841 router that i would like tu use as simple GRE VPN concentrator for 3 third party Ethernet/3G bridges with GRE capability.
My 1841 is installed in DMZ of a DSL modem/router with static IP. My third party terminals connect through GSM/EDGE/3G network and get dynamic IPs each new connection.
I just want those 3G bridges to be reachable with local IP addresses on my LAN, security is not critical for this first step.
I have a very good 1000 pages book to read about Cisco IPsec VPN settings for further purposes..
Your help would be very comforting...
I'm sure it's like bike.. i need someone to launch me and everything will come again as clear water
Regards,
Amaury
