Weird BGP problem and packet loss

Hi all.

I have a /30 configured with Fibrenet [MPLS circuit]. When I ping the other end of the /30 [] [BGP peer] using various MTU size, I experience no packet loss and the line is clean. However, when I apply the 'neighbor x.x.x.x allowas-in 2' on my router and then ping the line suffers from packet loss [between 5 and 10 %]. The BGP peer is up, I am receiving all the routes etc but surely configuring 'allowas-in' shouldn't cause ICMP packets to be dropped given I am only pinging the other end of the /30 address.

Fibrenet have confirmed they are not classifying ICMP packets. Any ideas?

BGP config:

router bgp 65498
no synchronization
bgp log-neighbor-changes
network mask
neighbor remote-as 64513
neighbor update-source FastEthernet0/0
neighbor allowas-in 2
neighbor password 7 104208140747000C040D247A
no auto-summary

Many thanks.
