# TCP packets are not forwarded out of a Bridge interface when SecureXL is on

**Product**: Security Gateways  
**Version**: R81.20, R82, R82.10  
**Last Modified**: 2026-07-23

## Symptoms
- TCP connections cannot be established for traffic traversing a bridge interface when SecureXL is enabled.
- ICMP traffic works as expected.
- Packet captures show that after traffic passes through the bridge interface, the VLAN tag is removed, and the destination and source MAC addresses are incorrect.
- TCP connectivity is restored when SecureXL is disabled or after switching SecureXL from UPPAK mode to KPPAK mode.

## Cause
This behavior occurs due to a software condition in the handling of VLAN-tagged traffic in Bridge Mode when SecureXL processes traffic in UPPAK mode. This condition affects Medium Path traffic processing, which results in incorrect packet modification.

This problem was fixed. The fix is included in:
