As shown in the figure below, a company uses the USG6600 firewall as the egress. The company has two egresses. Carrier A and carrier B share the egress load. When an engineer deploys the firewall, two egresses are added to the untrust zone at the same time. The user has joined the trust zone and made source NAT mapping. After the deployment, it is found that some users have normal access to the Internet, while some users have very slow access to the Internet, and even sometimes cannot access the Internet.
