Since it has a higher sequence number than 4, which was the last When packet 5 comes in, it is acknowledged by the PAC PAC MUST be silently discarded, or they may be reordered by the Not with reordering so out of sequence packets between the PNS and PPP does properly deal with the loss of packets, but To do so could cause problems,Īs proper PPP protocol operation is premised upon receiving packets When the PAC does receive packet 3, it MUST not attempt to transmit The PAC acknowledges packet 4, and mayĪssume packet 3 is lost. Because of rerouting in the internetwork, packet 4 arrives at Say, for example that a PNS sends packets 0 to 5 to a Occasionally packets lose their sequencing across a complicated RFC2637 - Point-to-Point Tunneling Protocol (PPTP) Lan mtu=1500, pptp tunnel mtu set to 1400 -> 3 fragments in GREįrame 44 ttl 247 Sequence number: 1159229 (182 bytes on wire, 182 bytes captured)įrame 46 ttl 247 Sequence number: 1159228 (1454 bytes on wire, 1454 bytes captured)įrame 47 ttl 247 Sequence number: 1159230 (446 bytes on wire, 446 bytes captured)įrame 52 ttl 247 Sequence number: 1159231 (1454 bytes on wire, 1454 bytes captured)įrame 53 ttl 247 Sequence number: 1159232 (182 bytes on wire, 182 bytes captured)įrame 56 ttl 247 Sequence number: 1159233 (446 bytes on wire, 446 bytes captured)įrame 45 Total Length: 124 Time to live: 59 Fragment offset: 1376įrame 48 Total Length: 388 Time to live: 59 Fragment offset: 1480įrame 54 Total Length: 1396 Time to live: 59 Fragment offset: 0įrame 55 Total Length: 124 Time to live: 59 Fragment offset: 1376įrame 57 Total Length: 388 Time to live: 59 Fragment offset: 1480 Has anyone a idee why both GRE packet receives but only the smaller icmp framgent is shown?
