i have two cisco routers, which are connected to one switch. On this switch, there are several servers connected as well.
When i connected the second cisco router, i got messages on the first router, that there is an ip address conflict. After a few minutes it seems as if the vpn tunnel on the first router breaks down because of this conflict. I'm not sure about this, but when i disconnected the second router again, the vpn tunnel could be established again. The vpn tunnel goes to another router via WAN and ends in the local class-c network, where both routers are in.
LAN 192.168.105.254 (255.255.255.0)
LAN IP 192.168.105.253 (255.255.255.0)
WAN IP 217.xxx.xxx.xxx
int fa 0/1
ip address 192.168.105.254 255.255.255.0
int fa 0/1
ip address 192.168.105.253 255.255.255.0
Could the /24 mask on the interfaces cause the conflicts?
From the servers, none has the ip 192.168.105.253 or 192.168.105.254 and if i disconnect Router2, the IP 192.168.105.253 is not reachable from any system on the switch.
