i'm new to the forum, so sry if i post on wrong forum...
i use open vpn on a client computer to connect to the server which is in another city... i can connect to the server and have no problems working... but i cant access my local router and my ip cameras, once i deactivate the open vpn connection i am able to connect to the router using his local ip 192.168.0.252 and also to the dvr server 192.168.0.29.
i use the same configuration of open vpn on 2 other pcs and they work good, i can also connect to the local router and the ip cameras....only with this pc i have the problems...
this is my config, maybe it helps a bit... im new to this stuff, i hope someone can have a look

# If redirect-gateway is enabled, the client will redirect it's
# default network gateway through the VPN.
# It means the VPN connection will firstly connect to the VPN Server
# and then to the internet.
# (Please refer to the manual of OpenVPN for more information.)
