I have a question how can you GRE tunnel on a cisco router 800 series set for a site to site vpn ipsec + gre who can help me?

You cannot do much but you have to re-IP your LAN and WLAN.
R1
ip address 10.10.10.0 255.255.255.0 for LAN
ip address 10.10.20.0 255.255.255.0 for WLAN
R2
ip address 10.20.10.0 255.255.255.0 for LAN
ip address 10.20.20.0 255.255.255.0 for WLAN
Thanks

you should do that for each range of IP addresses

yes re-ip your network which will fix your duplicate fragmented networks from both ends.
you dont want to add individual static-route for individual network to tunnel interface on each router, then introduce routing protocol, which will exchange routes dynamically over the tunnel interface.

, it is possible to do so by means of a routing protocol such as OSPF and BGP in place of a static route to add

Yes, stay with OSPF or EIGRP and you do with BGP as well but BGP is for bigger network with gears about 1000 or more.

would configure OSPF how you do that though because then I tried to connect to another router
R1
router ospf 123
network 10.10.10.0 0.0.0.255 area 0
network 10.10.10.0 0.0.0.255 area 0
R2
router ospf 123
network 10.20.10.0 0.0.0.255 area 0
network 10.20.10.0 0.0.0.255 area 0

Apply this on Router1
interface Tunnel0
ip address 11.11.11.1 255.255.255.252
exit
router ospf 123
network 11.11.11.0 0.0.0.3
----------------------------------------------
Apply this on Router2
interface Tunnel0
ip address 11.11.11.2 255.255.255.252
exit
router ospf 123
network 11.11.11.0 0.0.0.3
-------------------------------------------------------------
When done, look for ospf neighbor on network 11.11.11.0
Piece of strong advise, please use tunnel interface on /30 mask, othewise if your network grows you will run into problems and please make sure your tunnel interface contain private-ip address "11.11.11.0" is a public address.
Hope that helps.

that have applied but can not connect to the other router?
03-20-2012 09:11 AM
Can you ping the public address of the each other routers?
03-20-2012 09:34 AM
yes I can ping the public ip address from R1 to R2 and to otherwise
03-20-2012 10:44 AM
I do not get this, why your default-gateway going to same IP on both routers: 195.197.160.1?
Try this on router one.
on router one:
ip route 84.197.174.182 255.255.255.255 GigabitEthernet0
on router two:
ip route 84.197.161.59 255.255.255.255 GigabitEthernet0
Just to be sure, please also add this line below on both routers, "ip routing"
Please let me know.
thanks
