Features in 86251-05
Patch 86251-05 includes all issues resolved and enhancements released in
previous patches for Software Release 2.5.1, and the following enhancements:
UDP packets passed through the firewall by a reverse enhanced NAT rule
were getting an incorrect IP checksum. This caused IP to discard the
packets. This issue has been resolved.
SMTP proxy was falsely detecting third party relay under some
circumstances. This issue has been resolved.
DHCP policies are no longer stored in alphabetical order in the DYNAMIC
CONFIGURATION script because this did not work when the DHCP
INHERIT parameter was used.
If the Gratuitous ARP feature was enabled on an IP interface, and an ARP
packet arrived, (either ARP request, or reply) that had a Target IP address
that was equal to the SenderIP address, then the ARP cache was not
updated with the ARP packet’s source data. This issue has been resolved.
Deleting an IP MVR group range would only delete the last IP address of
the range from the multicast table, not the entire range. This issue has been
resolved.
RIPng was receiving invalid routes and packets. This issue has been
resolved.
When deleting a list associated with a policy, all rules were being deleted.
Now only the rules associated with the policy and list are deleted.
Level 1 This issue will cause significant interruption to network services, and
there is no work-around.
Level 2 This issue will cause interruption to network service, however there
is a work-around.
