Hi ppl,
Is there any known problem on GRE running over CEF? We have 2 checkpoint firewall uses GRE for peer to peer connection. Clients are trying to connect to the citrix server via over a wan (MPLS) thru the GRE tunnel.The GRE tunnel will run over our core before terminating at the other firewall.
Branch 1 --> Firewall (VPN) -->GRE-->CE-->PE-->WAN(MPLS)-->PE -->CE--GRE-->Core router-->Firewall (VPN) -->Citrix Server Farm.
