Hi experts,
I have a Cisco 1841 router which terminates the internet link for our ISP.
I recently bought a Layer 2 HWIC4ESW Ethernet WAN interface card. This is because I needed to add a second ISP for failover purposes.
I have created a VLAN, configured an IP address and assigned it on the 4 ports on the HWIC card which will be used for the WAN and local interface of the new ISP.
Whenver I try to ping any of the interfaces, it drops packets and I don't seem to have a clue why this is so. The patch code is fine. Please advise.

So when you ping from the swissport interface to your laptop, you lose about 40% of the packets, but when you ping from the other router (is that another router, or another interface on the same router?), you don't drop any.
What, specifically, are the symptoms that led you to test the pings, are you having connectivity issues? Have you verified that your new interfaces are not negotiating to half-duplex mode? That's a pretty common event if an HWIC is left to auto-negotiate.

Is 192.168.100.253 the inside interface on the router or one of the WAN interfaces?
Is 192.168.100.254 the inside interface on the router or one of the WAN interfaces?
Do you have 2 VLANs? Are 253 and 254 on different VLANs?
