Maybe the AP has been set that way for a long time. Did you recently change any firewall rules to block ICMP? If ICMP is working, PathMTU discovery can work and connections can deal with arbitrary MTU limits along the path. The TCP/IP stacks just lower the MSS until they no longer receive ICMP packet too big responses. -- Scott Lambert KC5MLE Unix SysAdmin lamb...@lambertfam.org _______________________________________________ Ubnt_users mailing list Ubnt_users@wispa.org http://lists.wispa.org/mailman/listinfo/ubnt_users
