Which type of traffic would most likely have problems when passing through a NAT device?

Telnet
IPsec
HTTP
ICMP
DNS

Explanation: IPsec protocols often perform integrity checks on packets when they are received to ensure that they have not been changed in transit from the source to the destination. Because NAT changes values in the headers as packets pass from inside to outside, these integrity checks can fail, thus causing the packets to be dropped at the destination.
